Overflow boxes and bubbles

I'm getting ready to rebuild my reef tank. I used to have a CPR overflow
but it made me madder than all getup. I had a rio venturi skimmer hooked up
to the air connection on the top of the overflow. The water flowing into
the box always created a bunch of air which the powerhead would pull out and
spit it in my tank! I recently heard of a pump that would do the same thing
but send the air laden water down into the sump. Have any of you heard of
this and if so, what is it and where can I get one!

Thanks in advance

Scott
