Check out the Garn web site under parts as well as the new section in the manuals for the new filter and its piping recommendations. It's designed to be a filter system but should have some impact on the stratification issue also. I've been waiting all summer on this as it was promised in the spring. Wanted to install before lay-up but at least can get it in before fall start-up I have a valve at the bottom front drain so will only have to drain down as far as the old thermometer plug holes to install and will front mount the pump and filter by the controller. I have some very light cloudy filaments and a flock Precision said should be filtered and was waiting for the Garn Guys to do the R&D on the plumbing. (Turns out they suggest exactly what I was planning ..........) I will run it full time for a few weeks (maybe even stir things up with a little compressed air) and then try to run it just on blower operation off the extra outlet in the control box and see how it goes. I was told this outlet has the current capacity to handle the pump. I'll keep you posted on the results. Dan
