Hello again, I bought my 20 mule Borax and now I just need to know how to use it to raise my PH level in my 15' by 36" above ground pool! I shocked it and now my chlorine is steady between 2-3 ppm but my PH seems to be lowering daily. Last night is was about a 6.8 or lower (my test kit only reads 6.8 or above) Can you all help me with the borax treatment? I don't have a Skimmer. ..not even sure what that is! I have just the filter system that cane with the pool, and on the top is where I put the 1 in chlorine tabs. Thanks so much!
