Sunsun 602/603 Canister Filter | Product Review

[@tooHecticX]

One and only person who showed how to set up and startup pumping... Thank You. You're THE BEST!!!

[@TheWaterBox]

Glad it helped

[@ivanoxx]

SAME!

[@Moshbearpig]

I run these on EVERY tank with seachem de*nitrate set on low flow making a powerfully effective denitrification machine. My nitrate problem was resolved within 3 or 4 months. Can't beat the price and so far they have all ran flawlessly. I test my water once a week and the nitrates are always low now even on heavily stocked tanks. I've been able to cut back on water changes with addition of these filters. Cheers

[@TheWaterBox]

very nice!

I use them as pre-filters on my Eheims. Drastically reduces maintenance requirements.

[@TheWaterBox]

Good to hear they work great this way!

[@GeneralGiggleMuffin]

How, the tubes and fitting are pretty thin on these. Did you have to do some modifications?

[@C8Kid]

I have it assisting my FluVal 406 w/ mechanical filtration in it, I plan to setup my Sun-Sun 3000 the same way.

[@enchiladabonito6629]

Years later after you posted this and mighty useful. The instructions are indeed garbage - Sunsun should hire you and buy the rights to this video to keep people sane and help them get this filter set up properly!!

[@TheWaterBox]

lol thanks

[@DeFreeseAquariums]

One of the keys I read in a few places is to lube the seal when doing maintenance on the canister. By doing so you keep the seal pliable so it does not disintegrate. Some have used a little vasoline on it. Also still a small hole in the intake tube, reason for this is if the canister fails it will not flood your floor. The small hole should be made about an inch or so below the water line. If the canister starts to leak out siphoning out your tank water when the water level drops below the hole it will break the suction stopping the flow and not empyting your tank on to the floor. Another informative vid brother.

[@TheWaterBox]

Excellent tip! Thanks buddy!

[@Rickyticky679]

The Water Box could you explain how you attached the water pumps to it to replace the given pump. A detailed explanation would be helpful or maybe even a video?

[@jamesd9337]

Good tip. I've been doing this for all my external filters for years and on the occasions my externals have failed this has been a life saver.

[@jensenbeachjay]

Great tip, BUT you shouldn't use Vaseline on on rubber seals or gaskets as it's petroleum based. The proper lube is silicone based. Use super lube or a pool-light grease (which will be a silicone base as well), as this will not degrade the rubber gasket over time.

[@TheWaterBox]

You have to get an external pump and swap it out.

[@cahjamur9849]

​@@TheWaterBox Yeah true, can you tell me the connector name from canister hose to pump, does it comes from the box? I don't see any connector like that here.

[@TheWaterBox]

You'd have to order one from ebay or amazon. Right now I can't find any listed because the whole covid stuff, supply has been scarce. Just keep doing searches for sunsun 602/603 parts and see if they come in sometime.

[@egoranonymous3223]

2020 update on the B series (the one with the pump): Just because the description says it comes with certain things, you should expect it to be missing some items that you will have to buy elsewhere. I bought this accidentally during lockdown thinking I was buying the one without a pump and it was missing everything but the tubing and two sponge filters. Don't waste your time trying to get the missing items, they will never come. After reading through literally 200 plus comments I found several old comments that said you will not get the missing pieces. This applies to Amazon purchases. Hope that helps. EDIT: August 2020, they both run somewhere in the $45. range.

[@TheWaterBox]

Thanks for the updates. It's cheap on ebay right now but you have to get it delivered from China

[@TheWaterBox]

Sure, if you want.

[@drakeespino50]

Hello! I recently bought a sunsun 603B canister. Im using stainless steel lily pipes with skimmer on my 10 gallon tank. Currently, from the top going down to the pump, I have lava rocks in mesh bag, lava rings and then lastly the white filter foam. The skimmer at the moment is not sucking as much as I hoped it would. I have to leave about 1/8 open down below the inflow so that the skimmer works. However, it is still not sucking enough. My question is, how do I resolve this? The skimmer works amazing when the inflow below is fully closed, but im worried about the debris under the tank wont get sucked up. Thank you!

[@TheWaterBox]

Sounds like you need a stronger pump.

[@flyfox3621]

How do you connect an external pump? There's only one hose fitting that fits the fixtures on the canister.

[@JoeNocella]

I have one of these arriving today for a ten gallon Betta tank. Thanks for the info. i noticed you added another small part along the output of the filter inside the bigger container. Is this another stage of filtration ?

[@TheWaterBox]

That's either another pump for more flow (need more on a 20g gallon tank but for a 10 it's good) or it's the Co2 diffuser which you don't need unless you're using pressurized Co2.

[@ernestendaya8994]

i have a question about the pump, did you plug in/used both pump or just the one that you both

[@TheWaterBox]

Just the one I switched out.

[@Whos.Asking]

How did you attached the replacement pumps on the canisters?

[@TheWaterBox]

Easiest way is to get the B version and use a small length of hose and attach it to the fitting then to the pump.

[@fhermo83]

Yea bruh I been running both models for about 6 months now on nano tanks of mine and haven't had any issues with the pumps they are pretty reliable so far the only thing that happened was I dropped one while doing my monthly cleaning and the valve on top broke clear off the top of the filter as you stated they are very cheaply made so handle with care but once you get them going there are consistently reliable the flow has never let up on yet but they are fairly new still I'll check in when it hits a year old

How is it after years ?

[@stevenhandy8264]

Hi Chung, great review and very helpful since I am about to install my new 603 to my 304b but I have a problem. The green hose from the 304b seems to be too big for the 603 fittings so how do you manage to tighten the nut on the hose?

[@TheWaterBox]

It's too big? Hmmm, that I'm not sure of. It should be the same size as the hoses. Did got the model WITHOUT the pump right? If you go the one with the pump then the fittings will be for smaller hose.

[@442caleb]

I am looking to get one of these for a 10 gallon planted tank. I am worried that the reports of a weak pump may cause issues with an inline c02 atomizer. Do you think i could run an inline c02 atomizer with this canister filter?

[@TheWaterBox]

It shouldn't matter with an inline atomizer... What matters in this case for an inline atomizer is the amount of psi coming out of your co2 regulator. I would worry for an inline reactor though. An atomizer will already create the tiny bubbles when it gets into the hose. The pump at this point pumps the bubbles out to the tank. It doesn't nothing else. With a higher gph flow though, it will help to diffuse the bubbles a little more though but that's about it. Many reactors rely on the gph on a pump to power a propeller or some kind of mechanism that depends on the power of the flow to diffuse the co2.

[@metranon]

@@TheWaterBox Hey Chung I ended up getting one of these 603b's and as you said, the pump wasn't adequate enough to power my c02 reactor, what is the maximum gph pump that I can strap to one of these bad boys?

[@alsaiahdavidm.decastro8756]

Is the canister filter great in a 75 gallon tank this sunsun canister filter

[@TheWaterBox]

No, it's way too small. For a 75 gallon, try the Sunsun Hw304B. You want something with at least 450gph. 500gph to be safe to clear any length of the hose form the filter to the tank to get at least 6x the flow rate in your tank.

[@myramorgan8974]

How do I hook up them hoses with with holes it it?

[@TheWaterBox]

You don't? I don't understand. What do you mean with holes in it?

[@TRUE_RODLER_slittino.sportivo]

When you say seals failure what do you mean? That it loses some water under the 4 small holes under the covering?

[@TheWaterBox]

There's a circular rubber seal around the lip. If that's not seated right or if it's worn down, it'll cause leaks. Pretty much the same for more filters.

[@shiyamaifrad8933]

Would work for 4foot tank?

Not for this filter. too small

[@ericmarasigan9458]

What is good with 50 gallons tank? I saw there is a new model 604b is this enough for 50 gallons tank? Or should i buy 303b?

There is no 604b but the 303b will work fine for a 50g... 304b will give you more margin for flow.

Yes, you might wanna go with the 602 as it's a perfect size for a 5g. You can adjust the flow with the ball valves that comes with it.

[@beyondthetank8192]

Great review Chung, very informative. I have been considering the Sunsun, but now I'm not so sure. Although, I do have a rimless tank I made that I could use one on. So far I'm not too fond of canister filters. I have a Fluval 305 that does not like coming apart for service. I broke the latch on it trying to get it to separate. Maybe the newer models come apart easier.

[@TheWaterBox]

Yeh, the fluval 305 is kinda a pain. I used to use the older model of the 305 13 years ago. They work, just a pain to take apart. How big is your tank? The sunsun 302 or larger models are way easier to deal with. I'll have a review of that one later. The 602/603 are quite simple and easy to maintain. It's just cheaply made. :/ The bigger models are made much better.

[@beyondthetank8192]

The rimless is a 40 gallon and I'm debating between a DIY sump above the tank or a canister filter. Possibly both because I intend to keep Plecos and I find they can be a bit dirty. It's in a small fish room I set up so a sump above the tank won't be too obtrusive and the advantage is I can access the media for cleaning very quickly and easily.

[@TheWaterBox]

Ah yeh for a 40, you'd go with the 302 or bigger then. And that is made way better than the small 602/603 and they work great. Good flow for a 40g. I like the above sump. I plan on doing that with one of my tanks to grow plants on top as well as for addition filtration. I'd go for both. Can't have too much filtration. Well, you can but a canister and above sump isn't too much.

[@tthimsel]

Thanks a lot for your amazing videos :) I would like to ask a question. How would you setup HW-602 (without pump) as a prefilter in regards to intake? I have seen that it is suggested for 602B-603B as the intake is coming into the canister from top and returning from the bottom back to the aquarium. However, a couple of people who used HW-602/603 as a prefilter is suggesting it from bottom to top somehow. Does that make sense for you? And, one more question just came to my mind. HW-602 hose is 16mm whereas my Eheim Ecco Pro 200 is using 12mm hose. I would need to use a 12-to-16mm adapter for intake into SunSun canister and then a 16-to-12mm adapter for return from SunSun to Eheim Canister if I wanna use it as a prefilter. Do you think this would cause any issues? Thank you in advance.

[@TheWaterBox]

I would hook up the 602/603 from top toe bottom, going into the actual filter (in one of my cases, a 302) and then from there back out to the tank. On the 16mm to 12mm is fine.It's not going to do anything really other than limit your flow to a 12mm tubing and the flow of your eheim canister. I'm assuming your hose length frmo the filter to the tank isn't like 20 feet long or anything?

[@tthimsel]

@@TheWaterBox Thanks a lot :) Nope, it is just around 1 meter, I guess. I can even place SunSun 602 on a higher level than Eheim. I hope it will not reduce the flow rate significantly.

[@TheWaterBox]

I usually get the ones with out the pumps but you can do it with the one that comes with the pump. Either Or BUT I perfect to get the ones without. It's just easier that way because the one with the pump is ALWAYS the same size. So if you get a 603 with a pump, the top attachment is a different size as where the pump is added it. It doesn't matter if it was the 602 though. It'll always be the same size regardless.

[@tanboi1105]

how do you disconnect the output for filter maintenance

[@TheWaterBox]

You have to unhinge and remove the output pipe from the tank so it doesn't siphon out the water. To make it easy, you can always get your own quick disconnect ball valve and install it after the pump and hose to where it outlets into the tank so call you have to is close it and disconnect the quick disconnect. but that might be more than it's worth the trouble and costs if you're just running one or two tanks.

Nice video .if I use 302 on 304b is it gonna cause any problem for pumps because 302 is rated for 250 gph and 304b is rated for 525 gph. My real concern is 304b will be getting 250gph but pumping out 525gph.input 250gph and out 525gph. Is that ok

I like your informative style. I was going to say information and style seperate but informative style seems to work well for you somehow.

[@TheWaterBox]

Thanks!

iwanna put this in my bedroom did it make some noise？

[@TheWaterBox]

The ones I have are pretty quiet. The only time it made noise was if there were air bubble in the filter but that would be the same for any filter and they eventually go away.

[@tingli9408]

The Water Box good!

@@tingli9408 good luck!

my aquarium size L120XW45XH60 costumize aquarium. what canister filter model use to my aquaruim.?

[@TheWaterBox]

Are those measurement in inches?

[@christinafacts444]

I'm looking to buy one of these for a 45g goldfish tank. I already have an aquaclear 110 (500gph) on it. Is there any point in doing that, or should I go one size up?

[@TheWaterBox]

I'd go a size up to the 302.

[@TheWaterBox]

Wait, you aquaclear 110 should be more than enough for your 45g. That's 11 cycles for a HOB filter so should be more than enough. No reason to get another filter unless you want a back up or something.

Hi, nice video. I have query. Sunsun HBL802 hanging canister and Sunsun 603B, which one is best for small tank like 45-50 litre? I would like to add biological media as well. Please guide.

[@TheWaterBox]

I don't know much about the HBL802 but the 602B is great and give you tons of space for bio media.

[@jeffcarpenter6306]

My 603B is causing micro bubbles. Any suggestions how to get rid of them?

[@TheWaterBox]

Sounds like you have air pockets in the filter. Try shaking it little and see if helps get rid of it. Any leaks anywhere? Maybe from the seals?

[@royyogafire]

have you ever used tetratec ex 2400?

[@TheWaterBox]

Nope.

[@raphaelandaya8335]

Can those intake pipes fit if u have a 3/4inch top bracket? Coz my tank is not rimless..

[@TheWaterBox]

You probably have to saw notches out of them at 3/4. It fit on my 10 gallon rim. My 30g I had to saw notches.

[@HarpreetKaur-xp5mj]

Its okay for a 8 gallon planted tank with inline heater????

[@TheWaterBox]

Sure. get the 302 one though (The smaller one)

[@tviray25]

Is this good for a 20-24 gal betta community tank? The HW-603B

[@TheWaterBox]

You might. You just load it up with just bio media and mechanical (sponges or floss) and change the pump to something that is pushing at least 140 gph you might be able to do it.

[@tviray25]

@@TheWaterBox what pump can you recommend to me to replace the stock pump? :)

[@TheWaterBox]

You would have to find something that's an external pump. I'd just search amazon and make sure it'll fit the hose. If you get the 603, it would be 3/4" hoses (It should be), if it's the 603b, it would be 1/2 " hoses

[@tviray25]

@@TheWaterBox Oh okay. Can you suggest a stronger external pump like the Cobalt pump you used to replace the 6w pump? :) I'm not entirely sure but can any external pump be used as replacement?

[@TheWaterBox]

I only recommend what I know works otherwise, I just look for something on amazon or ebay.

Canister Filter is my dream filter, but unfortunately those are not available here that's why i'm using a hang on the back filter. So I'm planning to purchase it online. Another great info and review buddy.

Awe, I'm sorry buddy. Hope you can find them online!

Tank is too big for this filter.

[@phinguyen3645]

Hello! What size tube of 602b? Thank you

[@TheWaterBox]

For 602b it should be 12mm or 1/2". The 602/603 without the B is 16mm or 5/8"

[@phinguyen3645]

The Water Box thank you .

[@TheWaterBox]

Welcome

[@melizzaginev5330]

Does this work as a skimmer too?

[@TheWaterBox]

I not sure what kind of skimmer you're looking to use but I don't think so.

[@RahulGupta-ff6ww]

I m saying that sun sun canister 302 is good for 20 gallon aquarium

[@TheWaterBox]

Sure! It might be a little big as it'll push a lot of flow into the tank but you can get a ball valve to control it.

[@liveswitmom]

Thanks for the help buddy!

[@winterume]

im lost, so 603b is just mainly used for pre-filter?

[@TheWaterBox]

Usually but I usually get the b if I want to install a more powerful pump because of the fitting will allow me to do that. If you get the A the fitting for the filter doesn't allow you to easily just hook up a hose between the filter and custom pump.

[@winterume]

@@TheWaterBox cant the 603b be a main filter? i only have 15 gal tank, im planning to buy it because its cheap and reliable in some ways.

[@TheWaterBox]

OH! Sorry, yeh, the 603b is the one with the pump. I mean I get the NON 603 for putting on my own pump.

[@winterume]

@@TheWaterBox i see, thank you a lot, really appreciate it!

[@secretndtellin]

what co2 external reactor is best for that canister filter?

[@TheWaterBox]

I'd always go with an inline mister myself but some people don't like it cause it "sprites" your tank. Depends on your canister filter. Some external reactors require high GPH so you need to read the product info. What works good is doing up a DIY external reactor where the co2 is injected into the chamber and the flow of the filter will push the co2 through bio balls (or something similar) to promote diffusion into the water before it gets into your tank.

[@secretndtellin]

The Water Box Thanks! big help...
