Annoying CPR overflow problem

[yeahcheetah]

My CPR overflow keeps on getting air bubbles trapped on the top, eventually causing a complete drain in my sump's return chamber, and making a bubble storm in my tank. Does anybody have a brilliant idea to prevent it? Appreciated.

Get the tank drilled. That's the best way to fix that problem.

You can use a small pump like an aqua-lifter that will continuously pump out water and air out from the top.

But I agree with Chief, Drill the tank.

larger return pump, the water in the overflow will move faster carrying the bubbles through. As dallas NYC said you can use a small pump to pull the air bubbles out. what some people do is run an airline tube up into the "U" tube of the overflow where the bubbles are and connect that to the venturi on a powerhead.

I ran a life reeef overflow box for five years and not once did I have a problem with it.

Same Here. I have 2 life reef boxes and not one problem in 3 years. They are the best in my opinion. I tried those cpr boxes and got rid of them in less then 2 months time.

cpr reccomends using an aqualifter pump to mantain syphon

....but a drilled tank is less hassle

I also had a CPR overflow with venturi powerhead connected (they didn't have the Aqualifter pump out at the time) and replaced it with 2 Amiracle overflow boxes. It looks like the same design as the Lifereef boxes. It hasn't failed me in the 3 years since I switched. I think the Amiracle's are also half the price of the Lifereef's.

Another happy user of a lifereef overflow. Never had a problem.
