Hello guys, I am now trying to put together my first big 50 gallons. I have bought it used. It came with a Fluval 305 and a sump (Aqueon ProFlex). The tank is also predrilled with some PVC going through it. The PVCs are different lengths. i am planning to use sand btw (not sure if it plays a role here) So while trying to figure it out, what goes where many questions pop into my head.

One thing that is important for me is to have a system that is secure and prevents any leakage on the floor. The only way i see this working for now is putting those 2 separately. The Canister will have it's in/out on the right side of the tank. And the sump(running on a separate pump) will be using one of the pvc (lower one) as an intake, add another water output somewhere and use the 2nd PVC (taller) to connect to sump in case of overflow. What do you think?
