What to use for circulation??

Thanks a lot CR, ima problably be getting one soon. Sorry i took so long to reply, im working the graveyard shift(from 6:00pm to 6:00am), and sometimes i actually got to get outside of my truck, but you have really helped me make my decision. Karma to you!!

 

I use a Mag 24 (2400 gph) hooked up to two sea swirls for my filtering duties, and a Gen-x PCX-40 (1190 gph) closed loop for circulation. It seems to work pretty good, I had some dead spots before I added the gen-x a couple of weeks ago.

 

OK I am always willing to try new things. Can someone explain a "closed loop". I keep reading about this and dont understand. Whats the purpose and how does it work.

 

It's just a pump that doesn't go through any filtering. Just an inlet to the pump and then back to the tank. It gives you flexibility if you have dead zones like I did and you don't want to add a bunch of power heads.
