Anybody use a CPR Overflow Box ?

clownfish06 · 09/01/2009, 08:30 PM

I am looking for the best HOB overflow and was wanting to know if this would be a good one to purchase? I just bought a 75 gallon tank and wanted to know the best way to set it up? I want to start with some live rock and a couple of fish and work my way up to a reef tank with 7-8 fish. Of course first I have to let the tank cycle before I start stocking tank. Tank is an All-Glass 48Lx18Wx20H.

Here is link to see box: http://www.cpraquatic.com/products/overflows.html

This is my opinion --- you couldn't pay me to use one on my tank. Don't care for the design that requires you to buy an aqua-lifter pump so that it will work correctly.

I am a fan of the U-tube HOB overflows. I have a LifeReef one on my 75, and it has been working flawlessly for 7+ years.

What is model of yours and around what price?

I have one now, have had it for years (CS-90). Its a pain to clean. Needs a venturi or AquaLifter pump to ensure syphon. Every few months I soak it in vinegar for a day to keep the buildup inside to a minimum. I'm sure there are bottle brushes that would help, but the openings are very small.

Need to get my RR 120 done so I can replace it. Would never buy one again.

Thats what I needed to know, thanks. Anybody got any suggestions on what I should go with?

I have the standard one --- 600 GPH I got it 7+ years ago, want to say it was $100, and I would gladly buy it again without thinking.

I was thinking about origionally going with the CPR also but after some research I changed my mind. Yesterday I ordered one of these. I've heard only great things about them and everyone says they work well and are good units!

+1 on not going with the aqua lifter style...

Also, I would drill it or have it drilled instead of using an overflow.

Can you drill an aquarium made by All-Glass , the lady I bought it from says it is made with tempered glass.

Email the manufacturer and ask if the back pane is tempered. They'll email you back with the answer. A lot of times only the botom pane is tempered. I have a bow front. The bottom and front are tempered, but the manufacturer emailed me back to let me know the back pane and sides are not.

I spent a fair amount of time looking into this a while back and concluded that Eshopps was a good choice.

I built my own out of acrylic. Had 0 previous experience working with the stuff. It was fun, rewarding and the thing works like dream. The only thing Ive changed is I added a critter guard to the inside box.

Total cost was about $25

i use the CPR with no problems. the key is to maintain it. Change the airline tubes periodically and throw a new diaphragm in the pump once a year. (I think its 2 bucks) I actually have mine running at full siphon, so its silent and moves a good amount of water.

hi toddrtrex,

just out of curiousity, why dont you like the ones that require an aqualifter pump to work? like what is the benefit of the u-tube overflows like the one you have? i was under the impression that the aqualifter ones were better to re-start a siphon if there's a brief power outage.

With a properly designed U-tube there is no need for additional equipment to restart the siphon after the power/main pump has been off. They just re-start, nothing else needed. Plus, the nipple that the airline for the aqua-lifter is attached to can become clogged, and wouldn't remove the air from the overflow.

I have had my main pump off for over 8 hours on a handful of occasion over the years, and the siphon start right back up --- I didn't have to do anything.
