Leptar;3053476; said:It will work just fine.... pop the impellers off the canisters so your flow isn't restricted as much...
The sump will be pushing the water into the canisters..
My only concern would be if you use pads in the canisters you might have a problem like what was stated before regarding the water level in the sump...
I would sell the canisters and current sump tank and upgrade to a larger sump tank... but that is just me..
Explain how the sump is going to push the water into the canisters. You do realize that the op is trying to use the canisters instead of a return pump, right?
