CPR CS90 DX Overflow with AquaLifter Pump

[Dr.Nate]

I think I'm gonna buy one on ebay....are they any good? And what return pump should I get? I was thinking of a Rio variable....HF12. That way I don't even need a ball valve, I can just adjust the Rio. I believe it's 0-840 gph and the CPR overflow is 600 gph. I'll have about 6' of head. Sound okay?

I would recommend against both the cpr and the rio pump. the CPR is quiet, but keeping the siphon is a problem. The aqualifter pump works fine, but they tend to go bad after a few months of operation. I would recommend a reguler C tube overflow. The rio is an iffy pump, you may get years of operation from it, but on the other hand it could fail under a year. Many people have problems with those pumps. For the same amount of flow I would recommend a mag drive 9.5 they are quiet and can be mounted either submersed or externally.

I have a Mag 9.5 and it is SILENT... can't tell it's there. I would also go with a U-tube... I have two on my 60 gal and they work great.

Regardless of what pump you get... it would be advisable to add in a ball valve anyways, just in case you'd ever need to adjust it. A tru-union joint is also good so that way you can take the assembly appart if you ever need to dismantle/clean it.

I have a CPR overflow (1400gph) and the aqualifter, never had any problems with them. The pump I use is a 1200 gph Iwasaki, it's a little bit noisy, like there is a jet underneath the tank... I guess it all depends on what you want and if you mind some noise, I have my tank in a room away from our master bedroom so we can't hear it at night. The other have good advice too.
