Aqualifter pump help asap!

[yesjenks]

Hello All,

I have a CPR CS overflow box. The aqua lifter pump attaches to the box to unsure constant suction. Today I noticed bubbles in my overflow box. I picked up the pump and my the overflow box stopped pulling the water. The aqua lifter is still sucking but not nearly strong enough.

What should I do?

I turned off my return pump as i don't want my tank to overflow.

Please help!

These pumps are great and apparently last forever if you replace the rubber diaphragms inside. The replacement kits are super cheap.
