This is my first year maintaining my own pool but have always had trouble keeping algae under control. Our pool is old and probably doesn't have the best circulation and also has a leak somewhere that we aren't planning to invest in fixing this season due to the need for a replaster after this season. I have to fill up a couple inches of water a week so I know that is messing with my chemical levels. I started a SLAM today because the water had been cloudy for several days and now is starting to turn green.
Pool is 35,000 gallon in ground plaster.
Test results from my home test kit:
PH 7.5
FC 0.5
CYA 20
I added 4 lbs of 73% Cal-hypo and brushed the sides.
My question is, how often do I test and shock again during the SLAM process? I think I read somewhere on here that it should be done twice a day but I can't find it again to clarify. Also, I saw that my CYA level should be 30 so I planned to add CYA to increase that but can I do that during the SLAM process or should I wait until after it is completed? If I understand correctly, increasing that level will help make my chlorine last longer.
