Okay. I'm going to build a closed loop that is temporarily run off a submerged pump. At a later date I'll switch the pump out but I figure the heat generated by the extra pump in the sump will be a wash when you consider zero powerheads inside of the main tank.
I found some black flexible pvc
at Home Depot (unfortunately no black elbows/T's) that I'm going to run in a full circle tight to the black plastic moulding at the top of the tank. I'll have 6 outlets (white pvc
t connections) hooked up to hopefully some adjustable loc-line outlets.
Question: Where can you get loc-line? Anywhere other than online?
