Very good pump, delivering alot of water. VERY silent, and the speed adjustment works perfectly. Very easy to install, a lot of fittings. Very good deal

Dcp 8000 running on my 120g. Silent. Time will tell if it lasts but for the price can afford a spare

Not too noisy, works flawlessly so far. Easy to control

I'm using DC-12000 for my 250L(66gal)saltwater fish tank. Runing DC-12000 with half power as it's loud when I use it with stronger power. Talking 'bout DCP-8000, It's very silent and I liked the control panel design better than DCT or DCS. I'm considering to purchase DCP-5000 or 6500 for my smaller tank.

Pump runs smooth with excellent capacity.
It is very silent and above expectations.

Threads are not that good but had no issues with it so far.
