This is newer plaster/pebble March 2015...I have been trying to keep my pH around 7.4 - 7.5 with TA around 95 - 100.....with that I have to add about 15 oz of acid a day and then every 3rd day or so bump up the TA with baking soda.
I had been keeping pH around 7.8, with TA around 85 - 90 but still added about 15 oz of acid daily, either way still using about the same amount daily.
Will the pH rise slow down as the plaster ages more or am I balancing the water wrong?
I understand the issue with pH reading with high chlorine and I have actually verified my numbers with the use of 2 commercial pH meters. I have also found that using the Taylor reagents, I can get reasonably accurate pH readings up to about 15 ppm FC readings. I should add, I now let the FC drift lower to about 9-10 for a very short time and check pH to again to get correct numbers.
CYA 150 (I know, will handle this later)(long story here)
Thanks for any recommendations....
