I live near Cincinnati and apparently have an atypical pool so the pool stores have no idea how to help me. I have a 20 year old gunite pool, Diamond Bright finish, StaRite 3 pump with cartridges and Turbo Clean caretaker system. I never had trouble balancing my water until 3 years ago. I follow the advice of the pool stores and it gets worse.
I took my water to be tested 4 days ago before doing anything. Granted, it was a pond. My test strip showed high pH, 0 free chlorine, good total alkalinity and low stabilizer.
Pool guy said throw in 12 gallons of liquid shock and a bottle of algaecide. I did. Next morning...low pH, O free chlorine, good total alkalinity, low stabilzer. Went back to pool store...was told to put in 16 more gallons of liquid shock. Next day, same readings.
Off to pool store #2...they said the chlorine was locked and that I needed to buy $165 worth of calcium hypochlorite.
Can I use calcium hypochlorite with a cartridge? I thought that clogged them.
Will that fix my problem?
Many thanks for anyone who knows what is going on.
