Sqwd???
 

Whos used these and what do you think of them?
Are they loud?
Im considering getting 2 to feed four closed loop outlets.

I ued one in a closed loop after about 3 months it jamed and I was unable to access it so it never changed direction. I have since taken down the tank and cleaned the SQWD it worked after that but never installed it

I've run one for 3 years now. I'm on my 2nd one. The first one lasted over 2 years. They are absolutely silent...require no power...but are very sensitive to sand. Ensure that you have a sponge filter in front of the return pump.

me and my brother both used scwds i really like them there cheap and reliabul
