Canisters are not needed and IMO
shouldn't be used. Water comes down by gravity, all you do is pump it up.
It works like this
You have water in the tank and in the sump. You pump water up to the tank that the tank can't hold. So with an overflow either hob
or a built in one ( works like a drain) makes the water.go back down. You'll have to watch to know how much gph
the overflow can handle so you don't push to much up to the tank.
What goes up must come down
