I finally have the plumber, steel people, electrician and the gunite people scheduled starting new week. I've decided to nix the in-floor cleaning system and go with a robot (PentairProwler 920). The SWG system consists of 4 IC60 units. And, the filtration will be two Pentair 420 cartilage filters. With the water features (falls, slide, etc.) I'm looking at 5 Pentair Intelliflo variable speed 3 hp pumps. I now checking (and reading on here) to see if the Pentair IntellipH unit works with this setup or if it even works that well. I have come to any firm conclusion on that yet. Any idea/thoughts would be appreciated. As things get underway, I'll keep you posted and take pictures along the way.
