Air in a Canister Filter

[Blindmelon119]

I have a Fluval FX-6 canister filter which I think I like. This is the first canister I've used. It resets itself each day and purges a lot of air. Any ideas on where the air might be coming from? I do not have a bubbler going.

Any splits in the inlet hose anywhere? On the inlet itself perhaps? I know my inlet is cracked but it's below the waterline so i just leave it.
