I have a 15 X42 AG 3900 gal
I only have the WalMart HTH 6 way kit but just ordered the TF100. Took a sample last Thursday to store results were:
PH 8.2 my reading at this time was off the chart
Calcium Hardness 310
TA 280 mine around 320
CYA 30 mine the black dot did not disappear
FC 1.56 mine the 1-2 section.
PH 7.9 my kit tested 7.5
Calcium Hardness 240
TA 120 my kit tested around 300
CYA 15 my kit black dot has never disappeared
For the past 2 weeks I use liquid chlorine only. I have added muriatic acid to drop PH to 7.2 and pointed my return jet up to make bubbles. The only other think I have used is sequsol (spelling?) because of filling with well water.
My water is clean but cloudy, just checked and is does seem a wee bit better. So I guess my question is will the high TA and when my PH was high could that be why my water is cloudy.
