sorry this maybe a stupid question but My canister filter was turned off for a while and when i re started it again all it did was throw out tiny bubbles... how do i get it running smoothly again? its been blowing bubbles for hours now...
You could always use a jug and a funnel to pour (tank) water down the outlet tube. This will clear any air in the canister, right through to the intake tube. You will be left with a little air in the outlet, but that is easier to clear than any that is trapped within the canister or intake (and saves taking a mouthful of tank water! )
