Product description
A JBL pH test for the 6.0–7.6 range, the span most relevant in many shrimp and planted tanks. pH shows how acidic or alkaline the water is: 7 is neutral, lower is more acidic.
Test at the same time of day and after water changes so you can compare. Follow the colour scale in the pack.
pH is linked to KH. Store the reagents as directed and replace them when they are past their best.
