This is the first year I am using a saltwater system with my intex 18'x42" round pool. I purchased a 2500gph pump as well (yah maybe overkill but so be it). I have followed the charts and added appropriate salt and stabilizer. When testing my pool, these are the results:
Free chlorine: low 0.5
pH: ok 7.2
alkalinity: high to very high
I have tried the boost function for the copper part..didnt seem to help. My manual says I need to run it at 2 hours for its size but maybe I should run longer? Haven't tried yet. I vacuumed out the pool but the next day I always seem to have stuff back on the bottom. Don't know if its dirt, algae or what. It looks more brownish. I cannot "backwash" or whatever that is as I just have a simple pool setup. We have been getting alot of rain so I do I need to add an algaecide or is my saltwater system supposed to take care of all that? I think I read that I need to get my alkalinity lowered but I do not know how. Please help me, and be careful with all the chemical abbreviations and pool talk because I don't really know what they all are lol.
