I am at the PS today getting my water tested.. There is a guy there in the same situation as me, high pH and high Alkalinity. He of course gets suckered into about $200 of BioGuard products. I just smiled knowing I spent $2.50 on a gal on Muriatic Acid to achieve the same result. I made certain to catch the guy out on the parking light. I told him about TFP and recommended he educate himself on BBB! He seemed very greatful and interested!
