17,000 gal AG pool. Here are my numbers from the pool store:

FC 1.5ppm
TC 1.5ppm
pH 7.7
Alk (w/stabilizer correction) 236
CYA 46ppm


They're saying my numbers are fine but I'm thinking the pH and Alk are high. I bought 4 gal 12.5% chlorine and a gal of muriatic acid. Exactly what do I need to do to get my numbers right? The water is crystal clear, although I had a bit of algae that I vacuumed to waste this morning. Pool looks good now.

Thanks!
