I am looking at using a canister filter to run GAC
and Phos remover and then to feed my fuge before returning the water back to the tank. Since the canister uses a syphon to get water out of the tank, what happens when the power goes out? Does it continue to draw water or is the pump sufficient to stop the water and hold the syphon until power is restored? I do not have the option of an overflow dedicated to the canister, but it will pull out of an integrated sump that has an overflow feeding it. TIA
for your help.
