Kent True pH Minus 16 Oz.

True pH Minus safely decreases pH of tap or pond water when used as directed. Use when preparing tap water for new ponds, or adding to make up for evaporation. Also use to correct for pH elevation over time due to natural processes. Most ponds do well with a pH in the range of 7 to 8. Test the pH. Add one ounce per 60 gallons of tap or pond water to lower pH. Wait 24 hours for full pH stabilization. Test again, if pH is still high, repeat process.
