Not Happy By shawn on 12/20/2013

first of all, not thrilled that you have to add a siphon pump to make this thing work! Second if you hard pipe the unit it is very loud.All the adjusting in the world wouldn't stop the gurgling. I had to make two pipes that fit into the drains (thank god for you tube). Overall i don't think i would not recommend this to anybody that wants to hard pipe their systems.
Good option By Daniel on 9/19/2013

If your tank is tempered like mine and you don't have a reef ready design, this is your best option. Just make sure you establish a water level for both your tank and sump. If either your siphon fails or your pump turns off you could have an overflow in your tank or your sump [double trouble]. Also be sure to use a good ball valve or two on your lines to regulate flow... It makes a bit too much noise, and the pre-filter will clog eventually, so do your maintenance, and this will work well for you....
Best alternative to a drilled tank By Tim on 5/2/2013

I've been running this set up for about a year. As other reviewers have noted, the aqua lifter pump maintains and restarts the siphon even in the event of a power outage. So far, I've had no problems. A couple of notes: 1) As an added precaution, I drilled a 1/8" hole in my return just below the surface of the water. In the event of a power failure, this will stop the return from back-siphoning into the sump and overflowing it; 2) If you have the proper sized sump for your tank, you can tinker with the water level in the sump, keeping it low enough to accommodate water flowing back from the tank if the power fails. Nothing is fool- or idiot-proof, but if you follow the instructions and do the maintenance, this is the next best thing.

Solid craftsmanship. It isn't as loud as I thought it would be, just keep the cover on. Like many equipment, regular maintain is a must.
CPR CS90 Overflow w/ Pump By Christian on 3/21/2013

I love this combo. Gives me peace of mind that my overflow siphon will always be going, even if power stops and it has to restart. This unit is exceptionally quiet, but I may add a durso standpipe to mine.
Excellent product! By Pat on 11/27/2012

This is probably the best option if you cannot drill your tank. I tried numerous scenarios to try to break the siphon and was unable to do so. Just make sure the outlet hose from the Aqualifter is under water either in the tank or the sump and you won't have a problem.
Very easy installation By Pat on 11/27/2012

This is probably the best option if you can't drill your tank. I have tried many scenarios and I cannot make this thing lose siphon. Even if you turn off the aqualifter it keeps on flowing, just make sure that the outlet hose from the aqualifter is under water, either in the tank or the sump.
CPR 102 By Michael on 11/21/2012

I've got it on a 75 gal. It's a little over-kill. Got this one because I figured if one pipe clogged I'd still have another pipe open. We turn all pumps off twice a day when we feed. Never a problem with siphon starting. Best part is it's completely silent. If I turn off my skimmer I can't even hear the aquarium running. So Nice! I absolutely love CPR Aquatics!

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.
