Learning how to balance. First time pool owner, first filled June 2015.
Only was testing with simple kit. No issues visible. Chlorine read about 4 and pH about 7.8.
SWG running at 50% entire time. Pump running 8am-4pm.
I added too much salt on 7/10, I misunderstood amount and Salt was up at 4800ppm. Since then have added water over time and it is now 3900ppm.
Throughout July and August pH stayed about 8, added maybe 30oz dry pH Down over that time. Water temp stayed about 80'.
Purchased and started testing with TF-100 kit:
pH about 8.2
Chlorine about 5
added about 20oz pH Down.
Water Temp 78'
Put solar pool cover (bubble wrap type) on main body of water, not the river or spa
Water Temp 72'
Chlorine 5+ more Gold looking than yellow
Cut cover to fit better, and added large section to almost all of river and half spa covered.
Water temp about 76'
Added about 1/2 gallon Muriatic acid
Chlorine 5+ gold looking
Water temp 74'
Uncovered 10/9/15 for most of the day and waterfall running.
I'm worried about CYA and too much Chlorine.
Should I be?
I have been comparing with Pool School and obviously I'm not close on some readings.
I was hoping adding Muriatic Acid to lower pH would affect the other readings.
