15x25 above ground pool with a sand filter & 1.5 motor. I opened the pool 10 days ago, water in the pool was clear with a few small leaves and a few small hills of sand in the bottom. I filled up the pool and using the K2005 test kit and the BBB method the kids started swimming. A few days later the water became cloudy, I followed the instructions from the test kit, I didn't discover TFP until yesterday, and things haven't gotten much better. My latest numbers are as follows;
Chlorine/bleach too high to read with test kit. Yesterday, before reading TFP, I started using Potassium Peroxymonosulfate, 2 bags last night. Filter running. My pool is in the sun all day, so I understand the CYA is allowed to be 70-80, correct? Should I replenish 20% of the water? Thanks for any help. I'm new to this site and am trying to read as much as I can.
