Power House Hard Type is the reason for a drop in pH level.
Discus, Arowana, Corydoras, Pleco, Guppy, and Platyfish, etc.

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.


Example of combined use of Power House Soft Type (controls pH rise) and Hard Type (controls pH drop), to create comfortable water conditions, using a hood filter.
●First stage of breeding
When setting up water in the early stage of breeding, use Power House Soft Type alone to control rise in pH level, for water that's more or less neutral. The photo shows an example of Power House Soft Type used alone in a hood filter.
●Second stage of breeding
In fish aquariums, due to various factors such as amounts of fish food and feces, etc., within 3 to 6 months, a larger than usual drop in pH level may occur. In this case, add Power House Hard Type in approximately half the amount of Soft Type. The ratio of the mixture of Soft Type and Hard Type is 1 to 0.5 in the photo.
●Third stage of breeding
If the pH level continues to drop even after taking the actions shown for the first 2 stages, add more Power House Hard Type, making the amounts of Soft and Hard Types equal. The ratio of the mixture of Soft Type and Hard Type is 1 to 1 in the photo.

Example of combined use of Power House Soft Type (controls pH rise) and Hard Type (controls pH drop), to create comfortable water conditions, using an external filter.
Soft Type used alone
When setting up water in the early stage of breeding, use Power House Soft Type alone to control the rise in pH level, for water that's more or less neutral. Soft Type alone is used for the hood filter in the photo.





Soft and Hard Type used together
When a drop in the pH level is seen, use the Soft Type together with the Hard Type. If the pH level continues to drop, gradually increase the amount of the Hard Type.
