I used it it works great, use it at night to counter the natural tendency of PH the water gets white dont get scare it is the way it works, use it every day until it raises the concentration of CAL. PO4 and every thing else. GOOD LUCK
Yess I put in one capful in the AM and then 2 at night when the lights are about to go out...and man does it ever make the water white!! Looks like Im pouring in milk!
