Each year that I open my pool here in New England I have the same problem, it takes until mid June to get the water to clean up to the point that i lose zero chlorine overnight and maintain it.
I perform the SLAM and have twice gotten a good OCLT only to have a setback shortly afterwards. The pool is using 0.5 to 1 gallon of chlorine per day. I did an OCLT last night and used 2.5ppm FC. I have again added 1.5 gallons of chloring to get 19ppm FC with CYA = 40. The water is crystal clear.
This has been going on for about a month now. I SLAM, I maintain and get a good OCLT and still the pool uses a gallon of chlorine per day and slips back to a failed OCLT. The only conclusion I can draw from this is that I'm getting a lot of new contaminants in the water daily. This is the third year using the TFP method and each year I've had the same problem. I'm thinking that it's the pollen and other stuf in the air. The pool is near a dozen white pines and a load of Forsythia.
Does anyone have any thoughts? Any help? Am I doing something wrong?
TiA, Mike.
