Product: Marine Test pH
Simple to use kit for determining pH levels in marine aquariums.
The TetraTest pH kit is a liquid kit, which works by changing the colour of a water sample in relation to the pH level. You simply need to compare the colour of the sample to the enclosed colour chart, to determine the pH.
Always read the instructions carefully prior to testing. We recommend testing for pH every 1-2 weeks.
