using canister filter as a water vac

[Greenman]

I had a quick question and it could be a silly one. If I would add a hose to the intake of my ehiem canister filter and used it to vacume sand to suck up debree and have clear water come out the other side. Would that be a really effective way for an algae vac and diatris cleanup?

I think it would suck your sand out of your tank
