Kent Marine True pH Minus safely lowers pH
of tap or aquarium water when used as directed. When used in conjunction with
Kent pH Stable, it will provide a buffered, acidic pH in the system. The use of
a good pH test kit is absolutely necessary while using this product, and the use
of an alkalinity test kit is strongly recommended! Caution: Many electronic pH
pens and probes drift over time and frequent calibration with a good test kit is
strongly recommended!
