Good Afternnon,
We have been maintaining our pool via the TFP methods for many years. We have not had ANY problems to speak of in several years.
This summer, I think we see some calcium precipitate on the pool walls. It reminds me of a saltwater aquarium that is run with the TA or Calcium too high and leaves a white powder on the glass. In our case, we have a white, powdery substance that is sticking to the walls. From the surface, it appears to slightly discolor the walls of the pool. Vigorous rubbing with your hand, or aggressively brushing with a nylon pool brush will release a white powder that almost instantly dissolves in water.
The pool is chlorinated with a SWG. Because of this, the pH constantly needs attention. It takes about a week for the pH to rise to 8.2. The addition of 1-1.25 gallons of muriatic acid brings the pH down to 7.2-7.4. We are trying, slowly, to bring the TA down some, and see if the pH swings are less.
Here are the numbers....
FC 8-9
pH 7.5 (today)
TA 90
CH 425
CYA 80
Salt 3180
BOR 15
Temp 88
CSI .04 (today)
Other than appearance, is this something to worry about?
ThankYou,
Bryan
