Filtration for a 90 gallon

[Connor333]

Hi, I already have a fluval 304 on my 90 but I think I need more. Do you think my AquaClear 150 would be enough? Also the space behind my tank is limited so I can't have one of those huge HOB filters. Thanks

Capacity wise, you are right, the 304 is not really enough if your tank is fully stocked. The AC 150 would add the necessary capacity, but isn't that a hang on model? I though you couldn't use such a beast?

Ya the 150 will fit behind my tank but I saw one AC 500 at the lfs and it LOOKED to wide but I am not sure. Does anyone know how wide the 500s are? Thanks

I'm pretty sure that a AC 500 is 4-1/4" 'deep' (that is, that's the required clearance behind the tank wall).

I'm certain an AC 300 is 3-7/8" deep.

I just measured behind my tank and it is about 4 and a half inches clearance. Guess I'll have to save up for a 300 or 500 This hobby is so expensive and addicting

Have you given any thought to getting a second canister, say an XP1 or XP2?? That way you have a backup in case the Fluval dies at least until you can get replacement parts.

I am running a 404 for main on my 90 gallon but I also have an XP1 to drive my UV. You can never have 'too' much filtration

>>> Never can have too much

You can actually. If the filters are generating to much current for your fish, (lake fish low energy environment fish), it can cause stress. In a planted tank, it can remove CO2. There are other scenarios.

The Aqua Clear is 30gallons MAX i use it on my 20 and i would mind a bit more filteration

I have an Aquaclear 500, a Fluval 404 and an Emperor 280 on my 90 gallon......that's probably too much.....

The fish seem to like it anyway. *nod*
