With aquarium water for fish such as discus, corydoras and pleco, depending on the number of fish, their size and the amount of fish food or feces, microbial nitrification activity can become very active, which sometimes results in a bigger drop than usual in pH level. The same is true for large fish like arowana, and in general,
fish aquariums often experience drops in pH level.
To avoid this situation, we recommend using Power House Soft Type to set up the water in the early stage of breeding, and over time as the fish grow in size and number, leading to an increase in the use of fish food, changing to using it together with Power House Hard Type. Hard Type's main component, wollastonite (calcium silicate), is of a mild nature and works to control the drop in pH level. Use Soft Type as the main additive to the water then gradually add the Hard Type, stabilizing water quality over the long term. |
