Yep, I think I wll do the closed loop with a manifold and a Dart as you suggest. I can see why there would be some head loss if it is 1" pipe. Is there a reason to use such small bore pipe? Also Rory- what do you mean by a 1/5" PVC length? And are all the fittings you suggest available at places like Home Depot or are they more specialized parts?
So what I am looking at now is a 500-1000 gph return pump to get the tank cycling and then adding the CL. If that's not enough flow I'll add the Tunze later.
Yep, there are a lot of options and I'm sure most of them will work but it is interesting to read about what others have done. I'm hoping to minimize the amount of money spent on re-doing something so it is good to be able to bounce the ideas off some of the more experienced folks out there.
