Green Killing Machine - Review

[@kalwiggy]

I'm pretty sure this was just an elaborate plan by your fish to clog the filter and force you to clean it, allowing for them to be removed from the tank and giving them the chance the roll out the window, getting back to the sea and the little clown fish to be reunited with his dad.

[@bradcoats5522]

Only thing your wrong about is it's not a clown but a barb. And hes not going to the sea but he is trying to make it out to be reunited with his dad. I dont think a seagull helped him but maybe. Maybe some other bird hope it wasnt the wrong bird that offered help

Hi Arnold! That is a remarkable result. Thank you for sharing the intro, treatment, and resulting clarity. I'm shopping around for an inline (partnered with a canister style filter) uv sterilizer. Wishing you all the best!

Frederick, not cluttering the tank with ugly filters is certainly preferable. At present, my tank is balanced and I don't need the uv filter. My GKM is still available if the problem recurs.

Thanks for this review. I bought on of these on your recommendation and my tank went from total green out (1cm visibility) to crystal clear in 4 days! I was astounded, having tried water changes and chemical treatments to no effect. I even did a full clear out of the tank and the green was back in couple of weeks. Then I got one of these. It was a reasonably expensive piece of kit so would no have risked buy it, if not for this review. Many thanks again!

This happens due to a overexposure to a high light, mine does the same, will turn fully green within 2 weeks, but this same filter clears it up and keeps it clean forever

Nice. I just bought a uv light for my african cichlid tank. Going to put it in a vertical pvc pipe with an airstone to bubble up the upward water flow. Hope it goes well like yours

[@Dirtbikeboy557]

I started a new 55 gal planted tank a month ago. Wood, rock, live plants, co2 etc. This is the first time I had a serious algae bloom’s. First it started with the normal cloudy water from the bacterial bloom (normal) after that went away I got a detritus bloom. Very bad one too it was the worst I’ve seen. After that cleared itself away with some help by me I got the green water bloom. First time I had this happen to me. Well after a bunch of research I went and got the GKM 9w. Only has been 24 hours and my tank is way more clear. Can’t wait to see what it looks like when it’s done. But my main question would be, do new aquariums go through a green algae bloom phase and it goes away? Or is it something that just can happen with new or old tanks and when it happens it wont go away until you act upon it?

[@arnoldsolof]

Hi GarageGoon. A green bloom is not a regular thing to expect to happen with a new tank setup. It can happen on a new or established tank when the conditions are right. When you get things balanced in your planted tank, you may no longer need the GKM (except on standby should another event occur). I used mine for about a year. The times before and following that period have been free of green water.

[@cmnr8487]

I have a 40 gal next to an East window, I honestly thought since it just got morning sun that I wouldn't have too much trouble w algae. My water is clear, but the algae I have grows only on the surface of gravel/rock and all over the glass. I can't put the tank in a different location, this is the only spot I have to put it. Would this work since my aglae is not free floating in the water, but instead is on surfaces? It's almost like it's attached to the glass, I have to scrub it off using a plastic scrubber every week.

[@arnoldsolof]

It will do nothing for your problem.

[@stevenjaskolka]

Can you actually see any light from the uv bulb? I dont see any light from my unit. Thanks

[@arnoldsolof]

No, the bulb is enclosed and the water being pumped around the bulb is exposed to the UV light.

[@MariaKim-k2q]

Hello! I need help. is it normal for the light bulb to stay on for only a few seconds after connecting the device to the socket?

[@arnoldsolof]

You can't see the bulb; it is enclosed. If you are referring to the power LED, that should remain on.

[@kameohosley2175]

My tanks always get an algea bloom within 2 weeks of set up but in 3-6 months it simmers down and I get only a little bit of algae every week. That being said, for some reason the algae spiked again (I have now had this particular tank for 3-4 years) so I got one of those. Cant wait for it to come! It is for only a 10 gallon but I dont know how else to get rid if green water and the other stuff without daily water changes, which I dont have time for.

[@SuperKX85]

How did it go? Work well?

[@paulasmith67]

I added mine in tonight after I had the same problem you just had. I had to move my Aquarium and I cleaned my substrate. I think that may be the reason my water turned green. I did two water changes in hopes of clearing up but no such luck so, I had added my GKM in hopes it will clear my water up.

[@arnoldsolof]

In situations where mechanical filtration of fine particles is suboptimal, doing water changes after running the GKM a few days would help physically remove the dead, clumped algae, hastening the clearing of the water. In my case, it wasn't necessary because my mechanical filtration is good.

[@caroleparker6191]

I need one of these. How many watts do I need to get for a 65 gal. freshwater aquarium?

[@arnoldsolof]

The 3-watt is rated up to 20 gallons. The 9-watt is rated up to 50 gallons. The 24-watt is rated up to 120 gallons. I'm using the 9-watt on a 40-gallon tank. Once the water has cleared I put it on a timer and only run it 4 hours a day. I would bet the 9-watt would work on a 65-gallon tank but it might take a couple of days longer to initially clear the water and you could run it more hours per day to maintain it clear (eg. 6 hours per day instead of 4). This is just a guesstimate.

[@petezet3532]

Hi, what is the name of this biggest plant? it's beautiful

[@arnoldsolof]

Pete, I think that is Cryptocoryne Undulata. When I was using optimal fertilizer dosing (lab test verified) for the plants it almost took over the entire aquarium. The leaves would rise above the surface of the water. It sends out side shoots from which new plants emerge. Since I backed off on the fertilization, its growth has been more manageable.

[@petezet3532]

Thank you very much for your answer :)

[@michelelogan152]

How do you know it is working. . I had my plug inside the aquarium opps. My has been running for a few days still green. I wonder what I did wrong. I see water coming out of the tube when I pulled it out

[@arnoldsolof]

When it's plugged in the green power light should come on. If you place a finger in front of the output port you should feel the water flow. The time to clear the water will vary and may take a week or two. Part of the variation is due to mechanical filtration which helps clear out the dead floating algae cells. That depends on your other filters.

[@TheWalk23]

Wondering weather the machine is still in use ? Definitely the lights were on too long per day. I do about six to eight hours a day. What did you do about a timer on the machine ?

[@arnoldsolof]

I stopped using it for about 2 to 3 years (wasn't necessary) then I got another algae bloom and used it again. After clearing the algae I run the Green Killing Machine on a timer for 4 hours a day to maintain the clarity.

[@sarge6870]

Wait...I just bought a GKM 9W and have it to where the output is at water top level. You have your submerged. I thought I was doing it right (from watching other videos). Am I doing it WRONG?

[@arnoldsolof]

Timothy, Check the video at 8Min 8Sec. The output is oriented on the top. It doesn't matter if it is below or slightly above the surface of the water. The pump and light are fully submersible. The controller & power supply need to stay dry.

[@ThierryC2373]

It happened to me too, all of a sudden I got an algae bloom. I had to buy a Green Killing machine and problem was gone in 3 days. The only drawback is that the blue sponge gets clogged very fast and requires a weekly cleaning at least.

[@arnoldsolof]

I read about the clogging of the sponge, but I have not experienced the problem. I have only cleaned the sponge once and it wasn't all that dirty. Leaving the device on only 4 hours per day is probably extending sponge cleaning intervals as well as UV bulb life.

[@2active4u]

I want to buy it but the 9Wat one says it’s for max 52 gallons tank. I have like a 63 gallon tank, do I need to buy the 24wat one ?

[@arnoldsolof]

The 9 watt model is officially rated to 220 liters which is 58 gallons. Once the water has cleared you only need to run it a small fraction of a day to maintain the water clear (put on a timer). My guess is it will take perhaps an extra day or 2 for the initial complete clearing of the water (9watt vs 24 watt models). Once clear you might need to run the smaller model slightly longer each day to maintain the clear water (eg. 2 to 4 hours instead of 1 to 2 hours.). For a 63 gallon tank I'd get the 9 watt model. It is smaller and easier to hide.

[@2active4u]

Arnold Solof Ok 🤝 Och when the water is clear and all, How do you prevent it from happening again ? I had my aquarium lights on for 8 hours each day but it was never the same time, because I’m not using a timer. So it was from 12 in the morning sometimes and from maybe 3 some other times. Should I reduce to maybe 6 hours every day and put it on a timer?

[@autumn1231]

I just bought one (9 watt) from Petco. Came out to $45 including tax. It was on sale and extra 10% for ordering online and pickup at the store. I have a 29 gallon with moderate algae bloom. I take immaculate care of the tank but there is way to much sunlight coming in the room. I am on hour 17 since installation and from reviews it looks like it is a 3 to 5 day process. I'm very optimistic based on the previous reviews.

[@romanscherbakov9561]

I got rid of those algae by weekly 30 percent water change, careful fish feeding once a day with no feeding at all after water change, and reducing light time from 12 to 10 hours. It took me a month.

[@peep_show8037]

Will this kill the beneficial bacteria needed in the tank?

[@arnoldsolof]

It will kill all bacteria in the water column (free floating). It has no effect on bacteria in filter media, the substrate, or on solid, non-free-floating objects that don't pass through the UV light. So, in summary, no.

[@RAGE666ification]

Do you take the original filter out to use the green killer

[@arnoldsolof]

Hi Stuart. No, you should leave the mechanical filtration working. The Green Killing Machine kills the algae cells or at least prevents them from dividing/reproducing. The dead cells tend to clump together and are filtered out by the mechanical filter. Without the mechanical filter, it would take longer for the water to clear.

Is this something that I could keep in all the time in the tank to prevent algae from happening? I want to start a new fish tank, but I hate dealing with the algae.

[@arnoldsolof]

Yes, I leave mine in the tank all the time. After clearing the water I put mine on a timer to come on only 4 hours per day to extend the bulb life. As far as "to prevent algae from happening", this controls the free floating algae cells in the water column that causes green colored water. It doesn't work on algae that grows on the surface of objects in the tank or on the walls of the tank.

@@arnoldsolof Thanks. I gonna do some water changes for 3 days straight first then see what happens. My algae looks like it's green water. So water changes might help. I was thinking about taking fish out & doing 100% water change. What do you think?

[@arnoldsolof]

If you take your fish out you are removing a source of nitrates/nitrites. It will make it difficult to achieve a long-term balance of import/export of nutrients and eventually get things stabilized because as soon as you put the fish back in, the tank will need to re-stabilize. You don't want to do 100% changes with the fish still in the tank to avoid stressing them. Depending on the nutrient content of the replacement water you are using it may also not solve the problem. Adding plants and having smaller/fewer fish will help. Again, the GKM will at least give you clear water now and you can enjoy your tank while working on achieving a long term balance. Once the balance is achieved you can remove the GKM. Some people would use the GKM so they won't have to achieve a balance and can get away with overpopulating the tank.

[@arnoldsolof]

Leonardo, the current is very slow, but even so, you should be able to feel it. Turn your other pumps off and suspend something flimsy like a string in front of the output hole to see if it pushes the string. If not, you might have a defective pump. Sometimes the impellers on the pumps can jam and have to be cleaned, but that shouldn't happen on a new pump. If the pump doesn't push the string, try taking the impeller out and re-seating it. Make sure everything is plugged in correctly.

[@twasbrillig33]

Timer or use when needed sounds like a good idea.

[@bmmyday2401]

What type of UV band is marked on the box for this sterilizer? Thank you.

[@arnoldsolof]

UV Light - 254 nm (disinfection) The UV light used, resided in the UVC range of the light spectrum. Specifically, they discovered that light in the 254 nanometer (nm) range was the most effective. When water pathogens are exposed to UV light, their cells become damaged and this damage inhibits reproduction. The frequency is not marked on the box of the GKM but it is specified on the material for its replacement bulb, although there is a typo saying mn instead of nm for the unit of frequency.

[@norcalbowhunter3264]

I’m at a point I might buy one of these. I did a blanket black out for 3 days, stopped giving water fertilizer to my plants, stopped feeding my fish, did a 70% water change, changed my hygger light to 6 hours 70% power, and I STILL have green water and I have no clue why. I do what everyone is saying to solve the issue, and the issue still persists. My readings are 7.7 ph, 0 ammonia, 0 nitrite, and below 5ppm nitrates. The only thing I can think of is maybe I went too heavy on the root tabs and it’s seeping into my water column? I have no idea but at the moment I only have 6 black skirt tetra in the 55 gallon so I really doubt they’re making to much waste. At this point I’m afraid I’m gonna kill my fish and plant trying to get rid of the stupid green algae and if a UV sterilizer works, then I might just use it. Even if it’s a bandaid fix. Nothing I’ve done has solved the issue and I’m desperate at this point.

Does it add flow or current to the tank? I ask because I keep betta and gups

[@arnoldsolof]

If your algae bloom is extremely dense, it might take a little longer to kill enough algae to visibly see the bloom starting to clear. Also, the dead algae cells will clump and then be removed by your mechanical filtration. If the mechanical filtration is not effective, it might take considerably longer to visibly see it. So give it a few more days and make sure your mechanical filtration has something like a floss layer to remove fine particles (clumped dead algae).

That would be great provided I wanted the uv lights on roughly the same amount as the regular lights. Since a 4 hours daily has been sufficient for the uv lights, I can go longer intervals between changing the uv bulb. I might be able to go even shorter with regards to the algae, but I want the uv light on to kill pathogenic organisms (bacteria, parasites, etc.) to protect the fish, in addition to controlling the algae.

I realize this is an old video but I have a question...I have an algae bloom going on in my Flowerhorn’s tank. I purchased the 24W version of the GKM today. Seeing via your comments that you’re running yours fairly regularly, how long would you say the lifespan is on the UV bulb itself?

[@arnoldsolof]

UV bulbs are rated for 9 months continuous use. After that their effect is decreased significantly. In my outdoor pond I have run one for 14 months so far continuously and it still seems to work. To extend the life of the GKM bulb, after initially clearing the algae bloom I put the GKM on a timer and only run it 4 hours per day. The algae remains controlled and I should get at least 54 months out of one bulb since I am only running it 1/6 of each day.

[@nightfire540]

Wow never had it that bad but didn’t know a uv sterilizer can do that

[@kawasakiman8965]

Wow why would u let the algae get that bad

[@SBS_Auto]

U need to fully plug the power plugs in. They snap in place

[@tarzan12052]

do u think this will work in 75 gallons? or should I get the higher watt 1?

[@lovingod4ever33]

tarzan12052 you will definitely need the 24watt! The 9watt is only up to 50 gallons.

[@tarzan12052]

lovingod4ever33 Thanx. I did get the 24watt and it worked great. Excellent product.

[@isaacfoster1206]

tarzan12052 are you able to use the 24 watt without a normal filter system

[@tarzan12052]

Isaac Foster Absolutely Not!

[@cwalke32477]

24 to clear it up. You could use a 9 to maintain it. 9 has cheaper bulbs, and uses less power. I let my 9 run 24/7

[@Moongazer101]

Interesting. I have an algae bloom problem in my fish tank currently. I realised the reviews of these products aren`t always genuine on the internet. If this product really works it would be fantastic.

[@arnoldsolof]

I don't work for the company. I haven't received any compensation for the review. I reported my experience.

[@Sparrow_Dynamic]

How the hell did you not notice the lights not turning off

[@arnoldsolof]

The tank is in the basement. I don't go into that part of the basement every day and especially during the times when the lights were programmed to shut off.

[@Sparrow_Dynamic]

Ahh i see

[@kyoatbites7865]

i use shrimp to keep my tank clear of algae

[@jpthsd]

that thing in the tank looks creepy!!

[@BenzFrank]

Believe it or not, you wouldn't have had that algae bloom if you didn't run out of CO2. Regardless of how long the lights are on...

Watched the whole video at regular speed. Nice video. I have to check out the green killing machine. 👍

[@michaelreffett6584]

Tried the 3 watt on a 20 gallon hex....total failure...water remained green as grass

[@arnoldsolof]

Michael, your experience is the exception to the rule. It makes me wonder why? Was your unit defective or what else was going on to cause the exception. If you ever figure it out, please post it here.

[@michaelreffett6584]

@@arnoldsolof I wish I had a definitive answer. The green indicator light is lit on the power box. I have it clipped appropriately to the filter and have nice flow in and out of the bulb housing. It has been 1 week. I question if the actual UV bulb is functioning

[@arnoldsolof]

@@michaelreffett6584 The time to clear is variable. Sometimes it happens in just a few days. Other times it can take 2 weeks or more. To clear the dead clumped algae cells you need some mechanical filtration too. Give it some more time. If it still doesn't clear the water after 3 weeks I would contact the company for a replacement.

[@michaelreffett6584]

@@arnoldsolof I removed the 3wt sterilizer and did a 10 gallon water change. I then installed the 9wt sterilizer and after 4 days my water is crystal clear. Water was still a bit cloudy with hints of green after water change. Perhaps the 3wt is not ample for 20 gal. But a happy ending nonetheless.

[@arnoldsolof]

@@michaelreffett6584 Glad to hear you got your water clear. I am using a Tetrapond 5-watt UV lamp on a 90-gallon outdoor pond and it works fine. Your water change removed half the dead/clumped algae cells. It makes me wonder about the adequacy of your mechanical filtration for fine particles. If not defective I would expect the 3-watt unit to work on a 20-gallon tank. Now that your water is clear you can put it on a timer to see how many hours a day it needs to be on to maintain water clarity. The fewer the hours on, the less frequent bulb changes are needed.

[@jdtracing6502]

Aqueon Algae Remover. A Capful would clear that up in just a few hours. I could not ever have believed that something could work so good. I have 6 large tanks and I have never had a problem with algae til one tank recently. Was so bad that I could not see my8" fish swimming around. I added a capful and came back 2 hours later and had to do a double-take. The algae was completely gone. It blew my mind that just a small amount of that stuff could neutralize it so quickly.

[@arnoldsolof]

Interesting. I looked at the 18 reviews of this product posted on Amazon and 14 of the 18 reviewers reported it killed their fish. A few, like you, reported rapid complete clearance of the algae with no discernible problems. It says it is safe for plants but I wonder if it is safe for all plants.

did it work as fast as his? i bought one and it’s been about 3 days and it hasn’t changed

[@sparkie92567]

Lots of Light,light,light & low oxygen, over feeding, are the main culprits of algae blooms...uv sterilizer is the perfect fix, besides the obvious fixes, you should only have lights on for a max of 4-6 hours then turn them off for at least 8 hours, that's if you have everything under control!!! Lots of Oxygen will also help, algae hates high oxygen levels & never do more than a 25% water change!!!

[@chelseamoore9526]

where is the follow up video?

[@arnoldsolof]

Chelsea, the follow up function is provided in the time lapse section of the video. I do have a playlist "planted tank updates" and you can find those videos by searching KZbin with the search terms "planted tank updates Arnold Solof".

[@ebededd9708]

9:42 that was the root problem

[@pauldeacon5615]

Hi! Very good video!! Those uv sterilizers are very good!! 😀

[@YOUNGTROPICA]

Long story short you should only use the uv sterilizer light or lamp when you realize your water is getting green it doesn’t have to be on everyday just use it when needed 🙂hope this was helpful

[@MrKwhited]

Change your t5 light bulbs and put new ones. When they get old they stop giving off all the good rays and start giving off the same light algae wants.

[@arnoldsolof]

There were no T5 lights at that time. There was an LED strip and a standard fluorescent fixture. Since then, the fluorescent fixture was removed.

[@C-MAGs]

Haha, you found the culprit for sure. I'm glad you are sorted. Did a fine job. :)

[@arnoldsolof]

Yeah, that was a big "oops"; I'd prefer not to state that actual word that I uttered:)

[@vd792]

so against which algae type does it work?

[@cwalke32477]

Free floating algae in the water column. It will not clear any algae growing on objects or glass

[@FishRfun]

Veer impressive...I just ordered one right now...the big one

[@arnoldsolof]

Yes, it is quite dramatic.

[@juan54950]

Would it work with a 55 gallon tank

[@arnoldsolof]

Yes, get the 9 watt version.

[@douglasfowler9076]

I have the 24 w in a 55 gallon tank probably an over kill but my tank looked just like his and I had tried several different things and nothing worked I added this and did a complete water change and now I have a clear water tank

[@michelelogan152]

It a Miracle!!! The water is clear today. Thanks everyone for the tips!!!

[@arnoldsolof]

Glad to hear.

[@TheVirajster]

Love my killing machine....one question. After one day of great pumping, it dribbles after a day. I have to unplug it , then plug it 1 day later, still a mild pump. PLEASE HELP

[@arnoldsolof]

I think you are saying that the pump output decreases drastically after 1 day; that it improves somewhat after power cycling it, but doesn't have much output. The pump is purposefully a weak pump with a low output so as to increase the contact time of water with the UV light. If, however, there was a major decrease from its original output I would take the pump apart and clean the impeller and the recess the impeller sits in. Perhaps a piece of gravel or a small snail got in there interfering with the impeller movement. If you can't get the pump back to its original output, I'd contact the company for a replacement pump.

[@lucicat5492]

....a couple of fish died.... "one was never found".... I'm really not surprised by that! Holy crap that's thick.
