CS100DX Deluxe Model Overflow Box w/ Lid & AquaLifter Pump

Excellent product. The image does not show everything. The deluxes includes the lid (almost completely eliminates all noise) as well as the aqualifter pump....which I highly recommend with the inline filter.This product exceeded my expectations. Functions perfectly. Once up and running I pulled the power and let the water back siphone into the sump. Upon plugging back in after about 30 seconds of gurgling and the aqualifter romoving air the syphon continued and the system was back up and running. Highly recommend if your tank is not drilled and are looking for a HOB overflow box!

I received CPR overflow box that day and found out was cracked. But I still like to give the product and seller five starts. Because I know that wasn’t seller’s fault it’s damn post office throwing the package. I contacted seller next day and he provided excellent customer services I got new one very quick with excellent condition. I installed it works like champ good design and strong flow rate. It’s perfect for an existing aquarium wants to have a sump filtration.

I actually have these on a few tanks. I like these a lot better than the ones with tubes. It’s a overflow box and it does exactly what it’s supposed to. I would definitely recommend this over ones with the tubes any day of the week. If I ever bought a tank again that wasn’t drilled I would definitely recommend this.

It works. It's easy to set up. The main drawback is that it's very loud. I'm going to try to put a flow control valve on the drain tube to restrict flow a bit on the hopes that raising the water leven in the drain section on the box will quiet it down some.

The best overflow I have had in the last 18 years. Super quiet and flows well. Easy setup and cleaning are really a plus. Must use a Aqualifter with the small filter ad-on for this to make it work really well.

Wao! Amazing product. I am so so happy with this overflow box. It was extremely easy to install and so silent. I highly recommend it. It comes with a TOMS pump which is usually worth around $24.95. Great buy. Thanks

Classical chinese product. Made of very thin and flimsy material. It was working up to the moment of splitting glue joints in corners. I used this on saltwater aquarium with salinity 1.025 checked frequently. Maybe to much or used to much salt???? Responsible for flood in my basement. I will buy different brand to replace this piece of JUNK.Definitely not recommending this product to anyone. Not worth the money.
