I'd heard some negative reviews/rants about overflows so after doing some searching I found out about Lifereef (they call theirs a Prefilter Box). Its rated for 600gph.

It costs ~$120US, and when I got mine hooked up (45gal+29gal sump, mag9.5) it took about 5mins to get the flow rate balanced and its almost silent. There is no airline or any of that sort of thing, except the first time you set it up to get rid of the original air bubble.

I've had it running for about 6mo's now & I have no problems with it breaking suction when its running, when I do a water change or when I have a power outage.

I looked at these Prefilter Box's I liked them and they sounded like they would be a good fit if you have the extra$$$ I did get a used CPR90 cheep and a aqua lifter no problems with this setup.

i just got (yesterday) a CPR90 for my 30G tank, so thats 600GPH on my 30 gal dont have to worry about putting a valve on the overflow it will work regardless of your pump keeping up or not as mine rated double what my pump is

awesome.. good to hear.. at first, the most common thing I kept hearing was "you cant spell crap without CPR" but no one had real experiance.. it was all just a friend of a friends uncles mothers stepchild (Jimmy) having a problem.

Also just contemplating going sumpless for the time.. getting a good quality skimmer that can be hang-on or in-sump.. so if one day I have more time and space to do a good sump and get it all baffled up correctly and what not.

if you go sumpless you don't need an overflow, i got my CPR and once i tuned it, its really quiet and works perfect, my pump puts out about 300GPH and the overflow is about 600, but even if i stop the overflow it catches up to the pump pretty easily
