I plan on running my canister filter inside my sump because i ran out of room going up to the tank. (my tank only has 2 1" holes drilled on the top, and built in overflows) right now i have a uv filter circulating inside the sump of the wet dry also off a powerhead. there is no way i can run the canister up into the tank without drilling new holes. I just want to make sure it will be effective enough or would it be a waste.
How effective is a canister filter when used in the sump?
- Thread starter infin
- Start date
Theoretically once the water goes through the trickle, the bacteria has broken down the ammonia and nitrites. So the water in the sump would be "clean". So in theory it would be ineffective to filter the sump water. My $0.02, I could be totally wrong though

Is the reason you want a canister to increase mechanical filtration??
The canister has to be well below the water level of the tank.
I'm imagining that if you run it from the sump, you wont have enough gravitational force to maintain the water pressure for water cycling.
Is there no way you can drill more holes?! Or maybe upgrade the sump and increase its's mechanical filtration capability.
Since MOST canisters are gravity fed, as JS was saying.. you will have to make sure it's below the sump...
just hook the canister up to your tank.. your over flow will usualy get most of the top crap and witht he canister in the tank, you can get a bit more of the middle/bottom crap!

I believe a canister has to be 2 feet below the water surface it's filtering.....Leave the canny alone, let directly filter the tank instead of the sump....If you want, stick a light on your sump and grow some pond plants....

im not sure if this canister is gravity fed or not, its an eheim 2250 and the inlet is on the bottom and the return is on the top from a pump. i wish i could drill another hole, but i dont trust drilling into the tank with it filled.
It is gravity fed, and would not work. Why not just put it in over the top of the rim of the aquarium, you don't have to put it in through a drilled hole. Just get some extra tubing if you need it, and go all the way up over the rim into the tank, then you will suck all the junk off the bottom as well as skim the surface.
Canning a sump would be a good idea if the sump is used as a collector for a battery of smaller tanks fed from a return manifold, and drained back to the sump. In theory you could use one XP3 to filter 15 ten gallon tanks!
But if you were going to the trouble of plumbing a battery of tanks this way, why not fabricate a wet/dry system in your sump eliminating the need for a cannister? Because you can never have to much filtration and the can could be used for other media like carbon and purigen etc.

i wish i could do that, my tank is acrylic and the top only has 4 openings that are far away from the edges. posting a picture for what im talking about. the other side is identical to the left side. i have only the one hole where i have one canister filter hooked up already to, and on the other side is the return for the wet/dry.
My question is why would you want to run a canaster when you have the superiour filtration of the sump? Sumps are the best way to filter in MHO
