Hi All, new pool owner here, have been learning a lot and I think I've got my chemistry pretty dialed in, but have a couple of detailed questions. See below results from my latest test (I'm using the TF-100).
1. Should I raise the calcium to 300? Or should I wait for it to potentially dip below 250? My assumption was that I'd like to avoid leaching calcium from the pool walls. My tap water replacement is very soft at 50 and my last 2 months of CH have been right between 275 and 250 with little change, but expect with more replacement water coming in with summer evaporation it will start to lower the CH further.
2. My tap water pH is off the scales high, i.e. measures above 8.2 and is a deep red/purple when testing. My last month of test results for the pool were right at 7.5, but I just saw it creep to 7.8 in my latest test this morning. Should I add acid to bring it down to 7.5 or let it ride at 7.8 until it starts to get higher? With summer rolling around I imagine evaporation will increase which means my higher pH replacement tap water becoming more present in the pool.
FC = 5
pH = 7.8
TA = 80
CH = 250
CYA = 45
CC = .5 (has been 0 that past two months and saw this just slip to .5 this morning)
Thanks!
