My TF-100 test kit arrived 5 days sooner than expected! So now I finally have accurate results to use the TFP method...
CYA 25 (exactly half way between 20 and 30)
So I plan on reducing the TA by using muriatic acid. I was hoping to get this at Walmart... do they keep it in the pool section or where do I have to go to find this? Is it sold under another name like CYA is (stabilizer)?
Pool math says to add 20 oz of chlorine, 8.7 oz of muriatic acid (20 baume) and 3.6 oz of stabilizer. I am going to pour the chlorine and acid in front of the return jet and put the stabilizer in the skimmer basket.
Am I on the right track??
Also, when testing TA, I noticed that the water flashed red for a second and then turned clear. Is this what I was looking for? I noticed a few times that the water would be a mix of red and green, then go back to being solid green when I swirled it around.
