I just bought a house with a pool. I started off with some algae issues due to a high ascorbic acid treatment the prior owner did, which caused the pool to have 0 FC for a few days without our knowledge. That seems to be resolving after a shock with bleach. I took a water sample to the pool store, and wanted to see what you all think about their recommendations. Here are their test results:
FC 8ppm (this was the day after my bleach treatment)
Hardness 20 ppm
Alkalinity 37 ppm (with stabilizer correction)
CYA 10 ppm
Phosphate 1200 ppb
Their first recommendation is to reduce the phosphate level by adding 12 oz of SeaKlear phosphate remover. Then, they want me to add 25 lb alkalinity plus (or baking soda). Then 40 lb calcium. Then 5 lb stabilizer "a little at a time in the skimmer."
I know that each of these additions will probably affect other levels in turn, so I want to be careful about everything that goes into the pool.
Thanks for the help!
