I opened my pool sunday and water looked pretty good. On the initial test my results were FC=0, CC=0, CYA=40, and PH=7.4. i added bleach to get to shock level and have had it there 2 days. Pool looks great and i plan on performing the overnight chlorine loss test tonight. Do i need to add algaecide?
Also, my cya is almost exactly the same as last year. Is this normal since i haven't had to replace much water?
