Plant Essential™ Buffer KH 5 Litres

Plant Essential™ Buffer KH 5 Litres

Increases pH Stability and CO2 Availability.

Alongside temperature, salinity, GH and pH; KH is one of the most important water parameters in your aquarium. Different plant species may require specific dKH ranges; these parameters are often not met due to influences such as low carbon dioxide or the presence of buffers. As a result the environment for your aquarium is not optimum and may cause stress to your inhabitants. Plant Essential™ Buffer does not contain any added sodium therefore it will act to increase KH without increasing sodium. The relationship between dKH and available carbon dioxide is positive, meaning that by having healthy amounts of KH will help to allow more carbon dioxide to be available for your plants. Plant Essential™ Buffer also acts as a pH stabiliser, meaning that when influences such as carbon dioxide or buffers attempt to change pH, the change will be minimised. We recommend conducting research into the preferred KH range of your aquarium’s inhabitants and adjusting your dose to obtain your desired KH. This product contains no added sodium, nitrate or phosphate.
