To do a water change of 100l could I stick the intake of the canister filter in my aging drum and the out put in the aquarium?
And (this is genius (mabey)) then attach gravel vac to intake of canister filter and stick out put out window?
Mabey the aging bin has to be same height as tank, but that is just a technicality(sp).
Is the new but aged water ok going through filter media?
Will this work or will I screw up the canister filter?
