- Deluxe CS150 with Lid and Aqua Lifter - CPR Aquatics
A built-in overflow is the most efficient method of draining aquarium water to a filter. If your aquarium does not have built-in overflow, CPR Continuous Siphon Overflows/Prefilters are the best means for getting water from an aquarium to a filter system. They quietly skim up to six times more water than units with tubes.
The advantages of CPR Continuous Siphon Overflows/Prefilters include:
- Adjustable water level allows you to easily change the level in your tank
- Black top reduces algae growth
- Plastic screen to prevent fish loss
All Deluxe CPR CS Overflows come with the Aqualifter Pump and acrylic lid for quieter operation.
CPR Continuous Siphon Overflows are used to transport water from the tank to your sump. Deluxe models include the aqua lifter to help maintain a full siphon.

Works great, until it doesn’t By jeff on 12/5/2019jeff wouldn't recommend this product to a friendHad this for 4 years. Worked very well (once I installed a durso to quiet it down) for 2 years. Then the aqualifter went tu. Luckily, I had an extra. You have to have a spare on hand when, not if, it fails.
Second disaster happened yesterday, and is actually a bigger problem. The overflow slowly built up deposits internally that restricted flow. It finally caused enough restriction that it couldn’t keep up with the pump, and my tank overflowed. The real problem is that there is no way to reach the internal passageway to clean it out and fully open it back up. Though I partially cleaned it enough to get things working properly, I will be replacing this immediately.
Pump is weakest link By Matthew on 10/18/2018Matthew wouldn't recommend this product to a friendThe design of the overflow is good. It is noisy so had to custom build a drain, but still more noise than I like. The weakest link is the Aqua Lifter pump. It failed after about 4 months breaking my siphon... I am looking for an alternative solution. Until another pump solution is offered I cannot recommend this overflow.
great product for design By Scott on 7/12/2017Scott would recommend this product to a friendInitially bought this product as I did not want to drill my 160 gallon. Well made, thick acrylic which performed fine. That 1.5 inch bulkhead can really move water as I was using a Vectra L1. Products are only as good as the weakest link. The $20 lift pump was a concern. So after a few months without problems I ordered the 16 inch synergy overflow. I started with the CPR because I had an established tank. I did take a risk and drilled my tank with with fish inside after lowering the water level. No problems with the drill. Amazing how a cheap $20 drill goes through glass. The synergy installed easily. Really love 3 1.5 inch bulkheads. You never wished you had smaller ones. I later ordered the synergy sump as it was plug and play with the 3 1.5 intakes! Thanks BRS!
JUNK! By SWANY on 4/24/2017SWANY wouldn't recommend this product to a friendthis is my 5th tank flood in 4 years... all from the junk pump 3 months first went out 1 week next went out... next lasted 1 year befor I replaced it and bam 1 month later pump stops working.....don't waist your time with this junk get the old trusted style that I had ran for 10 years with not a worry new stuff just not what it used to be...
great option By Derek on 11/24/2016Derek would recommend this product to a friendI am using one on my 150 gallon peninsula tank. I have two return pumps moving about 700 gph and the overflow is showing no issues.
How do you clean the inside of this thing? I've had this for a few months and the water flow is significantly lower. I clean the intake screen area, but there is no way to clean under the black section. This is an issue because it's gross in there and you can see the funk build up.
Have a great day!
