I have a 36 gallon tank. Would you recommend the 2213 or the 2211? The 2211 is rated up to a 40 gallon tank but i feel like i might be pushing it.

Definitely get the 2213. The media is different (better), the flow rate is higher (better), maintenance is easier and less frequent (better)and for the price difference it is well worth it.

I would use the 2213 because in my experience if it is rated for 40 then that is about max. I always go one or two sizes bigger.

My tank is 30 and this one works perfect since its right in the middle of the ranges. If u have a 20 I'd go with the smaller one.

Hi there. I think you are going to love you SeaClear aquarium. I put 25 lbs of substrate in mine and that seems to be plenty. More and you will have more problems keeping it clean. By the way, I just bought a Python water changer (on Amazon, look it up.) Now I can't imagine how I ever did without it! It makes weekly water changes a breeze. It may seem pricey if this is your first aquarium, but it's worth every penny. After you carry gallons of water back and forth for a few weeks, you'll see why. Aquariums are addictive and I now have a 50 gallon SeaClear and the 40 gallon. Would have more - even bigger - but I don't have the room! Good luck. Hi there.

I think that this would be a bit much for a 40 gallon tank. I would go for a lesser model. it works well on my 55 gallon tank but I would not go lower than that

I use a G90 on a 55gal tank. You should always use a larger filter than required on a given size tank. Bigger is better.

I think they come in different sizes. I have a 60 gallon and very pleased with the results. Seems to work as it says.

I am using this in a 55g tank, so yes, bigger is better in this case. First one I got was defective after 6 weeks, so crossing my fingers the replacement will be trouble free

One drop in services a 40 gallon tank for me. However. A smaller system such as yours will not be harmed with one drop in it will just be extra fresh and pleasant to clean up. Basically y one drop in per application is the rule.

I have 2 koralia 1650 in a 125 (72 inch length) and they are too much for the tank as a placed a partial obstruction in front to tame them down. I also have 2 850 which do not seem enough. For a 55 gallon I would stick with the 850 to 1000 range. I do like their magnetic base and wide column of water generated. I have mostly crushed coral salt tank with some aragonite sand. The sand is a problem with too much turbulence. Just one of the 1650 will transverse the whole 72 inch tank

It should work ok for a 30G tank. I have it on a 27G tank. It's rather weak even with almost no media in the treys. If you have saltwater tank with corals that need some current, this is too week. I know it's rated for much larger tank, but it's grossly overrated. I just got this too:( I'm really regretting it. It's unfortunate, but a powerhead will be needed for me:(Just to be clear, even if you have a fresh water tank, you liken't can't get enough flow to filter the whole tank with this power. Go up a model or 2 and get more power. Other than the lack of power, I do like this unit. I just wish that they have marketed it with the right GPH, and that I have purchased a more powerful one.

I have 3 tanks and find it best to have one on each side for my larger tanks 155 and 265. I have only one on my 55 gallon. I would go with one large on one side and see how that does, it wont hurt to add a smaller one one the right side if needed.

I've had several fluvals from 305,406, and fx6. The two smaller ones I've had for 5+ years and both still work great my fx6 is built even better then those two and I've had it for 10 months with no problems at all. The 406 was used for two years on a turtle tank worked great.

Twin 30 or 40 gal tanks with an automatic change-over regulator would be a pretty good working arrangement. Keep in mind, the bigger the tanks the heavier they are when you take them in to get filled. ;-)

I am using the 300 watt in a 120 gallon for aquaculture, it seems to handle very well, even outside. I would probably use 2 or a larger one for 300 gallon?

I don't recommend 30 Gallons tank. I bought this for 10 gallon tank. It was not enough.And I found a problem. Connection is weak.(from light parts to AC adaptor)

I have the next size up canister, the 2215, and clean it once a month by rinsing the media in newly removed tank water and replacing the finishing pad when needed. I have a light fish load, so your fish load may also come in to play as far as cleaning frequency.

On the front of the box it says it is good up to 30 gallons. I have a 20 gallon tank myself but I use the next one larger and it does a great job.
