I hope this is in the right area of the forums. Let me start off with a little background. I worked on 14 pools and 7 hot tubs all outside for 10 years. Recently changed jobs and now take care of 1 indoor pool for the last 3 months with no problems. Here is the issue I'm having now. Last thursday morning I went to backwash the pool and blew the shaft seal on the pump motor, thus causing a leak and having to shut down pool for 1 1/2 days to get parts to fix pump. For the down time the pool stayed crystal clear. Fixed the pump and turned on friday afternoon. I came into work on saturday to check chemicals in the pool and it was so cloudy that you could not see the bottom drain cover (5' pool depth). Pool is running a sand filter that is clogging up on a daily basis. I'll get new chemical readings tonight and post to see if someone can give me a hand.
