5 Ways To Manage The pH Level In The Koi Pond

The stable pH of your water is vital for your Koi and Goldfish. The best pH levels for a Koi or Goldfish pond is between 7.0 and 8.6. The regular measurement of pH levels is a must. Unhealthy pH levels can cause great harm to the ecosystem of your beloved fish and endanger their life.

5 Ways To Manage The pH Level In The Koi Pond

What causes the pH to destabilize is simple chemistry. The most common reason is the exchange cycle of carbon dioxide in plants. Typically during the day plants give more oxygen, but at night they produce the CO2.

All decaying vegetation, rain, and limestone can also cause the pH to change. Neutral to moderately alkaline pH levels can be managed by keeping the water filtration system well maintained. You can use some of the following methods to maintain them:

• Water additives are often used to maintain water quality. They block the ammonia, nitrite, or heavy metals that are present in your pond water.  When you have unstable pH levels, ammonia will be highly toxic for your fish. Any sudden change in the pH can have a grave effect on your fish. There are some specialized pH buffer and adjusting water additives that can also be largely used for pH control.
• Other than water conditioners, daily water changes will help account for the buffering and help you maintain the balanced pH of your pond. Using demineralized and dechlorinated water is one of the steps into lowering the high pH levels. However, it is important to change only a certain percentage of the water, or you may inflict damage on your developed ecosystem.
• In Japan, a popular practice is having oyster shells in some of the filters for maintaining a more stable pH.

• Baking soda is another component that will affect the pH levels in your pond’s water.
• Algae control in the pond is also a factor. If you reduce and control the algae, the pH will not be as high.
