I've been using the TFP method on my above ground salt water pool for the last 3 years. The first 2 years it was easy. I stayed on top of it and never had any problems. This year I am struggling. Water has been slightly cloudy since opening and I can not get it clear. Lately it has taken on a slight green tint.
The mystery is that my numbers have always been solid/spot on. Here they are from my last test:
Pump run time: 12 hours at 100% generation
I haven't done a slam because my numbers have been right on. But I'm thinking it's my only option at this point. I wanted to come to the professionals first and see if I was missing anything. Could the sand in my filter need replacing (it's only 3 years old)?
