looking for any size cpr overflow

[Bill 6069]

If you are still looking I have two CPR CS102's available.
The first is used and in good condition. The second is new unused with an Aqua lifter pump.
I can send pictures if you are interested

I would go with a u-tube designed overflow.

The cpr units are far less reliable.

Google "life reef overflow".

Anything that has a similar design and doesn't rely on an aqualifter is better.
