hi all! okay, after a year of love/hate relationship with the pool, i'm ready to make the effort to turn this into only a loving relationship! Since the day we took ownership of our house/pool, the cya was always 100+. I'm guessing now that it was well over 100, and this obviously caused problems. We also inherited some mustard algae that i'm thinking was hiding out in the 50 degree water and showed up as things got warmer last year. I spent a lot of time and wasted plenty of chlorine 'shocking' the pool, keeping things fairly clean for a week or so until the algae would return. This would repeat all summer long with the problem being those 'shocks' never got close to shock level with our cya being so high.
Wanting to avoid this cycle again, i bit the bullet and drained approximately 40-50% of the pool yesterday. It finished filling early this morning and i checked the numbers about 2 hours after that. Here they are (~25k gallons):
fc = 0.5
ph = 8.2
ta = 150
ch = 300
cya = 80
I was hoping the cya was going to end up around 50-60 but oh well. At least i know the number now and i can work with that. I was also hoping ta and ph were going to be lower but this can be dealt with. What i'd appreciate is some input on my course of action now. Ultimately, my goal is to shock and rid the pool of all algae. I also know the ph needs to be lowered and i'm guessing ta as well, but should that be done prior to shocking? Can it be done while i'm shocking? after? If we want to start using the pool soon, would i be okay to frequently add acid to maintain a lower ph and hope the ta drifts down over time, or should i lower ph and aerate? anything else i need to address? I appreciate the help!!! thanks
