hello,

i have a cpr c90overflow (flowrate of 600gph) for my 60gallon tank (my return pump is a dolphin with a rate of 570gph). just browsing around...heard some bad experiences with this type of overflow? can anybody help clarify?

thanks.

I gradually loose siphon on mine. About every 3 days I need to take the air line off the power head and suck out the air. I hate the taste of saltwater! That's a real pain, but it does the job. I don't plan on buying another though.

I've been using a cpr overflow for about 5 months and I have never had to suck the air out of it. I use a Hagen 301 powerhead with it and it seems to work very well....

The only thing I find is that sponge in the overflow has to be cleaned every week.

thanks for the reply. after reading thro the archives, i've decided to get a tank with an built-in overflow. lucky for me that i haven't really done anything to the tank (still empty as i do my research) and my lfs will exchange it for one with a overflow.

thanks everyone,

That's the best way to go. I'll never buy a tank that isn't drilled again. The plumbing is just so much easier.
