I checked my pool, and the pH just right, but the alkalinity is high. What kind of solution should I put in the pool?


You need to add Muriatic acid to reduce the TA, but remember that any acid will lower the level of the pH too. So the best thing is to add Muriatic acid to the pool to lower the TA down between 100 - 125 ppm, then add 20 Mule Team Borax to raise the pH to the recommended levels between 7.2 and 7.8. This might take a couple of days, remember to take accurate readings while fixing the problem.
