pH up powder 1kg bag.

Use only 1 tablespoon of pH up per 100L at a time. Test before and after use. Do not use more than the recommended dose.


pH in ponds

pH is the measure of acidity and alkalinity in your pond. Generally we try to keep it at a measurement of about 7 which indicates neutral water. Lower readings indicate acidity while higher readings indicate alkalinity. koi and goldfish favour alkalinity over acidity so are happy with readings up to 8.5.

Several factors can contribute to low pH levels in a fish pond:

  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.


Dosing pH up

It is very easy to overshoot the amount of this product that you use causing the parameters to jump up too high too quickly. pH up should always be added slowly in a few doses always making sure to test between uses. 

We recommend adding a small amount, waiting 12 – 24 hours before testing again and if it is still reading too low repeating the process until you are happy with it.

In order to dose this product safely you will require a pH test kit. You can find these HERE.
