| pH is an important factor to consider in aquariums that is often looked over. In order to maintain a preferable pH level, the Controsoil substrate includes kH buffering. kH is a reading of carbonate ions in the water column. Carbonate acts as a pH buffer by absorbing the acidity and preventing it from reaching low pH levels. This acts as a safeguard to keep your pH stable until all carbonate ions have been occupied with an acidic proton. The more kH in one’s water, the more buffering capacity it will have. |
