yea the old system ran on 2 hammerhead pumps and 1 high pressure pump that ran the skimmer. It was about perfect water temp in the winter, but during the summer it always wanted to get hot. Hopefully the new pumps wont create as much heat. I'm also adding a UV system, so not sure I will gain to much overall.
I like it the way it was. Are you changing anything other than filtration?
My apologies if I missed it, but what are the new pumps you will be running?
What UV set up are you adding?
