JBL - pH-Minus is a phosphate-free preparation to safely reduce the pH level. It contains a natural oak extract.
Before manipulating the pH-value, it is advisable to address the issue. There are 3 ways to lower the pH-value: by adding CO2 (carbon dioxide), by means of JBL pH-Minus or by using active peat (JBL TorMec activ). Of these three, peat has the weakest effect.
It is always most important to determine the KH (carbonate hardness) which stabilizes the pH-value in advance. With a KH under 4 °dKH the pH-value is so unstable, that the slightest amounts of pH-Minus or CO2 can lead to serious problems. In this case the carbonate hardness should be adjusted to 4 - 8° dKH prior to use. (with JBL AquaDur).
Please check every influence on pH with a pH test!
