Got my TF-100 kit earlier in the week and have been itching to test my saltwater 25,000 gallon concrete (gunite??) pool....... Here we're my results as of today:
Ph 7.8 (good there).
Salt 3600 (although the internal panel says 3500).
FC 6.5 (lots of aeration due to spa fill construction and waterfalls).
TC 7.5 ( think its normal per pool school. Thoughts?)
CH 450 (ok, I know this is high. Water is super clear and clean).
My biggest red flag is TA being so high.......not sure impact of aeration...
Pool is on full automation, swg, intelliflo variable pump, de filter (cleaned last week), zodiac mx6 cleaner and runs for 8 hours per day on 2350 rpm with 6 psi pressure on de filter.
Penny for your thoughts on CH and TA readings.........
