DIY Closed loop


New member
Anyone here runnin a DIY Closed loop. I've been thinkin of doing one and would like to see some pictures or plans of one.
I don't want to drill my tank so this would be one that the pipes set on top of the tank..

I've done both kinds...drilled and not drilled...IMO...drill it...drilling a tank is really simple. Here's a pic of a tank I am building now with closed loop and scwd.<br>

anyone else have pics of closed loops? im also thinking of building one on my 150 gallon. i have a extra little giant model 2-mdq-sc laying in the garage. would that be powerfull enough for a 150 gallon barebottom with 8 powerheads on the closed loop?
