RO/DI Units For Beginners- Melev's Reef

[@jeremynon7594]

great video...this is probably the most elaborate video on how they work and why you need them!

[@TomoyaKun100]

This video actually made me more relieved after seeing the beginning of an installation of a more up to date RO/DI system that you featured for college tanks. Now I know I don't have to do any drilling or anything lol

[@pokegirl1332]

I'm just starting up my first salt water tank and have seen multiple very confusing videos on ro/di systems but this was so well explained with easy to understand words =) thanks so much

[@coralfish12g]

CuriousMew Yes! That was the goal of mine. Thanks for the comment!

[@Iron_Hypa]

Good video George, just purchased my first 4-stage RO-DI unit due to bad water from my LFS..

[@Turusolight]

2020 still hooking me up ;) man you're so young

[@elijahowen1727]

a tip: watch movies on kaldroStream. Me and my gf have been using it for watching a lot of movies recently.

[@bodiezeke9848]

@Elijah Owen Definitely, I have been watching on KaldroStream for months myself =)

[@W4RD1N8ER]

This is what I was looking for great explanation super simple now I have a great idea where to put it when I get one.

[@traceyrae8331]

This hobby has become my passion. Binge watching your videos. I subscribed and think your awesome

[@TheRealDrCube]

Great video. During normal operation, when you are done with filling do you let the unit and filters dry or do you keep it wet some how? I guess my question is about storage between uses. Thanks!

[@coralfish12g]

I don't do anything to them. I just leave them and I'm sure they dry on their own, but they might be still wet from the last time depending on how often you use it. I don't think that matters

[@clowngames6164]

can you store water for few days and use it again? few days I mean like 2-3 days. thanks and good video!

[@danielfonsexa3264]

my water bill was about $80 a month consistently. Once I started using my rodi 5 stage filter it jump to like $230 in a month ( I only used it to make 30 g) crazy!!

[@gm836]

daniel fonsexa dang. Looks like I'm sticking to freshwater then.

[@intox69]

What's a water bill?

[@lightthebeacons6940]

Never paid a water bill in my life..

[@Nick_Jarrett]

You sir would benefit more from a distiller.

[@talontd3727]

Do you live in the desert?! Lol

[@indispensablechicken9417]

quick question- if I have an rodi system, will i need a filter? or is the rodi system a filter. I am going to get a 150 gallon aquarium

[@marisawoods7791]

ik this is kinda late and everything but what kind of RO/DI filter for a 150 gallon saltwater reed aquarium for a starter. this video was awesome info thanks

[@coralfish12g]

Go check out melevsreef.com or Melevs Reef. He has another more expensive unit that would be great for you.

[@murkylynch2600]

I have a 13.5 gallon tank, I'm definitely doing this hobby on a budget, I'm not asking for trouble but I don't think that an RODI system is necessary for such a small, simple tank, what are some other (less expensive) ways to get salt water for water changes?

[@t3l3machus]

great video...a question ... so you make your. clean water to salted , just by adding salt after the process ,right??

[@coralfish12g]

Thanks, yes essentially the salt carries all the elements you need. So just add salt and then you are ready to go.

[@stewsaquarium1397]

Thanks mate, great vid I am now going to buy a Ro/Di, I didn't think it was so easy to set up

[@Archeious]

Awww it's a baby George. Thanks for the video.

[@voltij5-5-58]

hi i dont know if you will answer to this but im getting my first 20 gallon marine aquarium and have 80 dollar budget for an rodi machine

[@voltij5-5-58]

which one should i get

[@electricblueaquariums4821]

Great video! Going to look into getting my own system. How often do you change yr filters.

[@NathansWildLife]

When you make rodi water do you mix the salt after

[@kristalynn7877]

You did a great job explaining, I understand now lol thank you! This is the best video I’ve come across so far in regards to RO/DI Systems. 🙂

[@berniegrant2633]

Did you ever make the video of how to make ro/di water to salt water?? I'm very new to saltwater and fresh out of fresh water a friend of mine that got out of the hobby gave me his r o d i system it's made by BRS

[@jamescarter485]

I have one more question about the unit I got one and am waiting for it to come in, but I was curious when u turn your hose off and are done with everything, what do u you do with the water in all the champers, do u dump them out or just let them sit in there to the next water change?

[@coralfish12g]

I just let them sit there. I don't think it hurts anything.

[@chrisj.s.6094]

very informative and helpful and easy to understand thank you young man

[@fishrrelaxing9361]

Something I’ve always wondered.. can you use the waste water for freshwater tanks?

[@wendeeee7]

is it the same as the one we use for drinking water?

[@WashtubTimeMachine]

You are awesome George! Thank you for your "clear as day" information. Great videos!!

[@coralfish12g]

+Jeremy Williams I really tried doing it that way for these videos! Thanks Jeremy

[@multisturge]

Another great thing about making your own water rather than buying it from your LFS when it comes to money, think how often you end up coming out of the LFS with a load of other stuff when really you only said you was only going in to get the water. I'm saving up for a RODI system from Osmotics (think they might just be an UK company) but they really been helpful and forum sites too as I been put off by getting a unit because one video I saw was using a drill and installing a tap but I see how simple it really is. Thanks to osmotics' and reefer's support on forum sites I can make my unit portable (don't have an outdoor tap) by connecting it to my electric shower which would keep the pressure gauge reading up in theory. On average how long does it take to feel up the container with RODI water?

[@multisturge]

forgot to mention in the UK I pay £2.50 for 25litres of normal RO water with around 15ppm TDS and for not having a car I have to plan in advance with my parents to take me to my LFS to buy the refills, before my last refill I had a week of no RO water after my last water change until my refill so if my tank crashed from a spike during that week I would of had no water to fix the disaster as my LFS closes by the time my parents finish work.

[@coltonfey9491]

Hey great video! Could you give me a link or suggest a decent RO/DI unit for a 10 gallon salt water tank? Thanks!

[@coralfish12g]

The one I used in this video! The link is in the description. Tell him I sent you please!

[@Dieppaloveplants]

Thank u i just bougth lil by little for the salt water fish tank that i always wanted and lots of people told me ohhh is expensive ah blah blah and me serching youtube etc im ready thank u againg for the info cuz i thougth i was hard to do it

[@MrV8eater]

great video ? I been in this hobby for 2 years and was always confused about this machine so just bought water water from lfs thinking I was going to see up my tank... BTW can I buy this exact unit from amazon ?

[@coralfish12g]

I'm glad the video helped simplify it for you! You can buy this exact unit on www.melevsreef.com/

[@albertmanagbanag2012]

Thank you george very helpful video for a sw noob like me.

[@AZ-pp5qs]

Hi. I was wondering if I have saltwater tank with saltwater fish in it. Can I still use RODI water? instead of saltwater

[@coralfish12g]

+Jayden D_Thang This question doesn't make much sense to me. RODI water is freshwater without salt added to it.

[@AZ-pp5qs]

+CoralFish12g like I ment , if I have saltwater fish can I still use Rodi or I only get to use saltwater. ...

[@shifty51008]

+Jayden D_Thang you use the rodi water for the base water, then add your salt mix to the rodi water till you reach 35ppt or 1.026sg using a properly calibrated refractometer or hydrometer.

[@oluayanbiola7566]

so the water coming out of the black tube is safe to drink?

[@coralfish12g]

Hi Olu, No, the black does not go through the di so it would seem safe BUT, you have to remember that is the waste water from the ro so the ideal drinking water would come from the blue tube but before going into the di. I hope that makes sense.

[@oluayanbiola7566]

yep, it does. Thanks.

[@phile83084]

does his rodi kit come with a faucet diverter valve?

[@coralfish12g]

Phi Le Almost positive yes.. the website link is in the description and it will say on there

[@nataliex909]

How long do these systems usually last?

[@2InfinityRKX]

how long does it take to fill a 5 gallon? also can I hook it up to a kitchen sink?

[@uhohhotdog]

Robert Xiong I'd also like to know

[@joetaylor5281]

I WOULD LIKE TO KNOW AS WELL

[@Nick_Jarrett]

Well 50gpd (gallons per day) would be 2.4hrs, 1.2hr for 100gpd and with decent water and clean filters you'd waste about 4x (or use it on the plants)

[@Dartster]

So that’s how it is. Thanks! Very helpful video!👏😁👍

[@alinoor6293]

Great Video My reading in in on19 how do I get it to 0

[@dolbyblustar]

Fantastic video buddy. Very helpful and informative. How long roughly dose it take you to fill that water jug? Thanks again.

[@coralfish12g]

Thanks! About 1-2 hours

[@peterroy2348]

hey, would this be acceptable for a 35gallon tank? Got gifted a saltwater setup and it was a really poor setup.

[@Johnaubreyduncan]

Nice vid!!!. It is the R.O.membrain that does all the work not the DI stage. The R.O membrane should reject 98% of all the T.D.S. The DI stage only takes otut the last remaining 2/3ppm, mostly made up of heavy metals (copper, zink, alluminum ect...). Your BRITA water filter will not have an R.O membrain in it. It will only have carbon filters remove chlorine, and bad tates. The carbon filters on your R.O.D.I filter are only there to protect the R.O.membrane, and make it last. The water going into the R.O membrane will be about 50ppm. It should be 1 to 3 ppm coming out.

[@markmcdowell935]

Nice have one been doing it for years I needed this video 5 years ago when I first started in the hobby. Thanks it will be great for the beginners like you've said great video keep it up .☆☆☆☆☆

[@coralfish12g]

FishTankDoc. Always on top of the correct info. Thanks for sharing

[@marshreef1764]

I dont think the numbers work that way when your tap water is 700 TDS :-(

[@michaelross5674]

Can I use just ro water???

[@OldSalty22]

Did I hear you say 50 ppm coming out of the unit before the DI stage? If that's what it is then your membrane is shot. TDS should be less 10 or less before it reaches the DI.

[@lucifermorningstar-lk9ow]

Is it available in amazon?

[@mjslemmer7956]

How long can you store the RO/DI water before using it?

[@coralfish12g]

I don't think RO/DI water has a limit on that. It could be stored for as long as you need without a problem as long as it is out of direct sunlight.

[@mjslemmer7956]

CoralFish12g thanks!

[@genealameda1163]

Nice video but what happened to online coral series

[@coralfish12g]

Sometimes I get these impulses to make a few videos or maybe just one on a certain topic. I will try to come out with another Internet Corals video soon!

[@MAPAHaus5]

is filtered tap water ok to use? filtered through the ref?

[@coralfish12g]

Check with a TDS meter. Anything with more than 0 TDS is less than ideal.

[@ldballoon4]

Hey, George, how was the first semester?!

[@coralfish12g]

+Alex Kingcole Hi! It was pretty tough. Once my season starter time management became harder but I would rather be busy than doing nothing.

[@PaoRangerVang]

Wait so the bad water is good for drinking??

[@just_hexxy]

This was a very helpful video, Thank you!

[@pamkonen8593]

I purchased just a RO unit, I didn't realize there was a RO unit & a RO/DI unit. So I should have the RO/DI unit??

[@brettschneider8521]

Pam Konen yes get a rodi unit

[@pamkonen8593]

Got one! So far do good!

[@nickwees]

Where did you get your shirt

[@coralfish12g]

It is one of EcoTech Marine's shirts. You may be able to get one on their website.

[@emanuelberrum1]

i need an RO for a nanocube 24G... any recommendations ?

[@jamescarter485]

this may be a stupid question but what's the difference between a rodi unit vs a ro unit?

[@coralfish12g]

One makes a RO water and the other makes RODI water. The difference between the two can be learned in this video of mine: kzbin.info/www/bejne/qHXHlKR9ral_hJY

[@applehoe2592]

Can I use tap water for my corals is that fine

[@coralfish12g]

No it is not ok

[@Aquascape_Dreaming]

The city I live in, in Australia has extremely hard water. My brother's father in law has a reef tank and uses unfiltered tap water in his aquarium without any issues.

[@MAPAHaus5]

can i direct the water into the sump for topping off?

[@coralfish12g]

Yes, you could

[@ciddire]

Excellent video!

[@gleyvigonzalez972]

Hey would you please subject me a good one i got a 55 gallons tank

[@Jack72961]

Great video 👍

[@coralfish12g]

Thank you for the comment!

[@albaniansk8er]

What is the TDS meter used in this video?

[@coralfish12g]

It's just a generic one of Ebay, but Hanna Instruments makes a better one that I use now!

[@xtrememats]

That's a lot of tubes! Make sure you get an under sink cabinet mat from Xtreme Mats and a water sensor to prevent any water damage from the inevitable leak at ​xtrememats.com.

[@MrGva12886]

Can't I just buy water from the store ? Or from those machines that you can refill water

[@jceescorner4877]

Nice video.... Drinking DI water as you know is arguably not a good idea. DI water great for "Reef Usage". BulkReefSupply told me for drinking water they suggest their RO system which does not have the DI filter because the DI filter removes too much and might not be good to drink water with no minerals. It almost like distilled water being super "clean" and arguably some say it may not be healthy over time to drink DI or distilled water. Thanks for a great video and the ideas on how to save $$$ for your "fish tank" using the DI etc.

[@Aquascape_Dreaming]

Jcee's Corner this is actually nonsense. You get all the minerals you need through organic vegetables and meat. Drinking purified water cannot harm you as you are simply hydrating your body. I read a very interesting article on this very thing. I'll try to find the link again if you're interested.

[@cooldog393]

what is that intro music it's so familiar but so unfamiliar

[@coralfish12g]

+cooldog393 Odyssey by Wyld

[@jackiekearney]

how about the flashing the initial water?

[@coralfish12g]

If you mean't flushing, all you have to do is disconnect the DI canister from the rest of the unit and let it run for a few minutes in the beginning before you make your water. This protects and keeps your DI resin cleaner once you reconnect them.

[@vietxnameze]

Very informative.. Thanks

[@barnhartmd051977]

What about my freshwater aquarium?

[@hadleys_goldfish7322]

can i use tapwater for just clownfish

[@coralfish12g]

For fish only tanks, it's ok to use RO water.

[@mcslapbass]

Did I really just hear him say the word gauge like "gawj?"

[@philquinlanjr7143]

Gosh

[@borinvlogs]

first i thought it was american pronunciation. never heard of it in uk.

[@SunnyLee45101]

can i work for u

[@Jimsmith656]

Awesome video. I've been looking to get one of these units for so long and thought the installation was too difficult. But you made it look pretty straight forward. Will definitely be getting one now instead of making the constant trips to the LFS

[@coralfish12g]

Thanks!

[@MrAirtaz]

Old video, I know. Just wanted to say thanks. BTW, around my area it's only 0.30 a gallon of RODI water.

[@ant7773]

Great video, however you said gauge ( [geyj] ) wrong. sorry just an fyi for ya.

[@coralfish12g]

Anthony Litterilla Thanks Anthony. I mispronounce things occasionally, I do my best not to.

[@patrickedwards2795]

The word is f*cking gauge... Like how tf do you mispronounce that?? I'm done.. You've totally lost me.. It's honestly an everyday English word.. I'm just f*cking done.. "Gowg" 😂😂😂😂😂😂😂

CoralFish12g thank u man

[@deepreef10g9]

I've only got a 5gallon aquarium

[@nighthawk_king6960]

You realize you can use distilled water right? Reverse Osmosis water and Distilled are mostly the same, it's just that they're both filtered differently. For me, I don't really trust RODI systems since many of the ones I have bought have failed after 2-3 months. Distilled is the safest option, with it being filtered from evaporating water, cleaning it naturally. That's what I would rather rely on then an RODI system

[@rijaltanjung9506]

what's DI ?

[@coralfish12g]

Deionization 5:41

[@Tsagos]

I dont understand why is bad to drink the water after it passes through the DI unit. Its just plain water with nothing in it! All I know is we shouldn't drink JUST that and nothing else because we need the minerals that there are in any other water source. Anyone willing to explain to me where I'm wrong?

[@coralfish12g]

+Giorgos Tsagos Yeah, it is confusing, but apparently too much of the water without all those minerals is bad for you. I don't think if you drink a glass of it, it will be that bad. It is only if you drink that consistently more than regular water that it is harmful.

[@jeramiescott3364]

+Giorgos Tsagos Just google why its bad to drink distilled water, RO/Di water is the same thing.

[@shifty51008]

+Giorgos Tsagos it's not bad no matter what you read, you will get all the minerals you need from any food you eat or anything else you drink, but imo rodi water tastes like crap anyway

[@uhohhotdog]

shifty51008 yes it's bad because the pure water will absorb nutrients from your body as it passes through

[@ChuckFreeburg]

35 cents a gallon for RO in the neighboring town. But $9-12 in gas to get there lol

[@barretharms655]

Add salt distill your water with activated carbon in the Olympics reintroduce an appropriate amount of minerals and then enter just your brining salt everybody this is not a show this is a commercial

[@mm-zc2ny]

Good video but I think you should not be wasting that much water by just putting down the sink, Use it on the garden

[@coralfish12g]

Yes, I think I will make a video on tips for what to do with that water

[@multisturge]

yeah the waste water is very good to water the garden and any other plants you have around/in the house. RODI water has other uses too which helps your parents/partner be more happy to having the system in the hose especially if you're going to take up some space under the sink (except less trips to LFS). Can use it to clean the windows and tank glass, good to make tea (I'm in UK with hard water so my kettle gets covered in limescale) and baby formula if you have a baby, can also be used to fill up your car radiator.

[@coralfish12g]

multisturge Yes, these are all good. I do use it now on tea and watering

[@tommythecat0382]

agree. watched a ton of videos. They assume I know what the heck they are talking about. But for a beginner it was all greek. This wasn't.

[@VlTO.SPATAFORE]

Hey brah, that shirt making you look like a men in black in the beginning

[@oxiac6006]

I have a cup for ro/di

[@Lengsel7]

waste water for drinking? Wtf?

[@Nick_Jarrett]

The waste water is just the tap water with a higher tds, perfectly safe. I mean if your tds is 200 and it bumps it to the 250 then it's still below my 440!

[@Lengsel7]

But WHY would I drink it, if I have RO??? Psh!

[@gm836]

Seems like a waste of water 4 gallons lost for one gallon 😕

[@Nick_Jarrett]

You can buy pumps to pump the waste water back in so its about 1:1 waste or use a distiller which wastes none but uses a lot of electric

[@talontd3727]

You can contain it and use it for watering plants, drinking, etc.
