I have been reading the website with respect to increasing pH while maintaining TA.
I understand that Borax has two uses in TFP.
1. To increase the pH while having minimal effect on TA
2. As a CL stabilizer? Where one needs to maintain 50 ppm of Borate. I guess it helps decrease the amount of CL needed and makes the pool sparkle?
Recently I did a partial drain (40%) and my starting pH is below 6.8, obviously the lowest number on the test block. I fell into the trap of chasing the pH by adding baking soda. Please see my numbers below.
I really donít want to use Borax because I donít want the hassle of having to measure another test (borate levels), nor do I want something else in the pool that can only be decreased by removing water.
That brings me to my question regarding aeration. I have a submersible pump. What can I buy off the self to use as an aeration device? Does the water have to spray over the pool to be effective?
Thanks so much.
pH < 6.8
TA - 200
CH - 150
CYA - 28
