First, some background. I acquired a house with a pool 2 seasons ago ...struggled though one and a half of them to keep the pool reasonably algae free. Then, thankfully, I found this site and adopted TFP methods. And WOW!! is all I can say. I learned what "sparkling water" really meant. That felt great but lugging jugs of bleach, not so much. So, this year I'm thinking of adding a SWG. An IC40 with EasyTouch controller, to automate with my Intelliflow VS pump, to be exact. Is the IC40 a good size for 21k gallons?
As I'm in the process of planning the installation (have to rework my pvc lines anyway) and was wondering if 12-18 inches of straight pipe before the inlet is really necessary. Any opinions or experiences?
