  • good product By Ken on 1/26/2015

    If you are not able to get a pre-drilled tank these are great products. You can regulate the flow from the return pump and make it virtually silent. It can be difficult to clean but I have only had to do that on a few occasions. This is my second CPR overflow, the first was 10 years old and I had no problems with it, I damaged it moving my 75 to another room so this is a replacement. The aqualifter, I can take it or leave it. I was using a MaxiJet 1200 with the same results plus the added benefit of additional current.
  • lifter pump runtime By Greg on 12/22/2014

    If you are worried about the lifter pump failing after it has run so long it dies (I read this concern), what you can do is put a refractometer in line with the tubing. You could probably use a Smart ATO, and if it senses a refraction due to salt water it will be off, If the refractive index is that of air, it will turn on. Much like it behaves in a sump turning on an auto fill cycle. Seems like a lot of trouble though. The lifter pump is a safe guard against air pocket build up in your overflow and is not necessary for the overflow to run. It is a safe guard and certainly recommended. Much better than U-tubes.
  • CS90; The perfect HOB overflow By Greg on 12/21/2014

    Installed a CS90 w/lifter pump. Plugged it in. Done. Perfect. I too got a little gurgling at first however, then increased my flow to hold at about an inch above the head of the filter guard on the intake. Silent.
  • Excellent By Roger on 11/20/2014

    I've had this overflow for almost a year now. It works flawlessly. Easy to assemble and use.
  • Great Product By Bill on 9/7/2014

    I have been useing this over flow for about 8 years. I just replaced it because the nipple for the vaccume pump broke off. I have never had a siphon break in all those years. When the power goes off, it starts up quickly and resumes the flow. If you do not have a drilled tank, get this product
  • quality product By Eric on 7/26/2014

    Purchased this because I cannot drill holes in my tank. I was nervous when buying this because of it possibly failing, but it has been running constantly with no issues. When power goes out it drains into sump and when power comes back on the siphon restarts and works just like it should.
  • Good By Victor on 3/11/2014

    I have the CPR102 on my 75 gallon with 40gal sump. I like how quiet it is, it does need a little tweaking to get it quiet My Skimmer is louder than this
  • Does the job By Reefer368 on 3/4/2014

    I have the cs 150 for my 125 gallon tank and 40 gallon sump it is awesome except for the fact that my system is hard plumbed and it is pretty loud with the gurgling of the water
  • Works great very happy with it! By Jorge on 2/24/2014

    We are very happy with our choice and would say no problems at all with it.
  • CS90 Great product By O'D on 2/5/2014

    I originally went the cheapest/ugliest route and constructed overflows out of PVC via DIY videos on YouTube. While they were indeed cheap, functional, and gave a sense of accomplishment, it just didn't look good, and brought a constant fear factor knowing the flaws of that system. I was toying with the idea of drilling the tank, but soon decided a HOB overflow would be the safest route. These overflows are great, but I would like to know how long the pump will last until it burns out...while the siphon remains despite the pump being turned off (or if it died), if the power goes out and then comes back on and you're not there to start the siphon again, you could easily flood the tank and cause big problems. I would definitely say the pros out weigh what little cons there are with this. I'm not having any noise problems, but if you do, there are videos for standpipes to help with this.
