pH up 1kg

1. Decaying Organic Matter: Decomposing organic matter such as leaves, fish waste, or uneaten food can release acids, lowering the pH.
2. Rainfall: rainwater is naturally more acidic than our neutral tap water so can directly lead to the acidity of pond water.
3. Soil Composition: If the soil surrounding or underneath the pond is acidic, it can leach into the water.
4. Algal Growth: Algae can consume carbon dioxide during the night, leading to acidic water.
5. Mineral Content: Low levels of carbonate hardness (KH) can make the pond water more susceptible to acidity/alkalinity fluctuations.

Addressing these factors through proper pond maintenance, such as regular water testing, removing decaying matter, balancing the pond’s ecosystem, and adding buffers or neutralizing agents, can help stabilize pH levels for fish health.

If your reading is too low (i.e. below 7) we recommend adding a small amount of pH Up in order to get it back up to approximately 7.
