We like the product and the quietness of the flow; however, the pump worries me. If it were to fail, there would be an issue. We have not had any issues and do not have to worry about fish getting trapped.
Much better than Eshopps By john on 2/25/2012

A snail got sucked into the U tube of my Eshopps overflow and 10 gallons of saltwater ended up on our wood floor. Wish I had my tank drilled but the CPR 102 seems to be the next best thing. It is also much quieter than the Eshopps that I had modified with durso standpipes. The CPR DX overflows are plug and play.
BRS doesn't carry flexible corrugated PVC drain tubing. Made my own using 1.25" PVC spa hose found at HD. I cut to length and used PVC glue to 1" PVC piping for a leak free connection. Tried a hose clamp but that leaked. I think reinforced vinyl tubing, sold by BRS, is too stiff for this application and corrugated PVC tubing allows the return water to become more oxygenated.
I'm not a fan of using the foam filters that came with the CPR. I couldn't hear a sound level difference and foam filters can harbor algae which will add nitrates to a tank, if not regularly cleaned. Most reefs would have a sock filter where the return water enters the sump anyway.
Also bought a Ultra Float Switch (Ultralife Reef) that I'll mount in my sump to kill the main pump if the sump water goes too low, in the event that the lifter pump dies and I lose siphon (note to BrentB). BRS, you should carry these too. Making one from parts, sold by BRS, looks like more effort than necessary.
If you have a U tube overflow box, I would recommend replacing it with a CPR. Also having a low water kill switch in the sump would be a good idea.

This product works great, and looks great also. My only complaint would be its pricey for it being such a simple thing. But hey someone hasta make money.

Got the CS 102 for my 110 gallon and is working like a champ. It is a little pricey but I have used outer overflow box's that you don't pay much for at first. With this I have some piece of mind that I will not have a problem.
Great! By Ryan on 6/22/2011

I will never go back to the U tube overflows. They have way to many problems with loosing siphon! Never had a problem with the Aqualifter pump clogging. but i also use the aqualifter prefilter. Not a single overflow in over 5 years!
Poor Design By BrentB on 2/25/2011

The overflow is a nice unit but has a serious flaw....the aqualifter pump. I have been running these overflows for about a year and have had 3 overflows resulting in huge water damage. All three times the lifter pump failed and the units loosed siphon and the tank overflowed. If CPR would redesign the unit scrapping the need for the lifter pump it would be much better. I since then got rid of the CPR's and went back with the U-Tube overflow.....essentially failsafe
best there is By Blake on 11/18/2010

this is the only overflow that I have found to never loose siphon, even during power outages. I wish I had this before I ruined my living room floor and basement ceiling last year. The aqualifter really makes it foolproof.
