Calcium carbonate treats water with a pH greater than 6 and synthetic magnesium oxide will treat water with a pH below 6. Untreated water flows through the filter, which is filled with calcium carbonate (limestone) or a synthetic magnesium oxide medium. This material dissolves in the water and raises its pH level.

What does baking soda do for a koi pond?

What is the pH of a pond?

In an ideal world, your pH would read between 7 and 7.5 all of the time, but if this cannot be achieved don’t panic too much. Consistency is more important in recording pH levels. For instance, customers in South may have a tap water pH of 6.8 and an established pond pH of 7.2. It’s good as long as it is consistent. Areas in the North with hard tap water can have reading as low as 6.5, and again this will not be too detrimental as long as the water is consistent in pH throughout the year.

What is pH?

pH is a figure expressing the acidity or alkalinity of water. It is a 0-14 scale; one is the most acidic and fourteen is the most alkaline. A pH of 7 is classed as neutral. It is important to note that the difference between one pH reading and the next level up is ten times, not one. For example, a pH of 9 is ten times more alkaline than a pH of 8, and 100 times more alkaline than a pH of 7 (10 times 10).

Understanding pH in a koi pond. The pH is a measurement of hydrogen ions as acidity and hydroxyl ions as alkalinity in the pond water; pH 0 - 6.99 is acid; pH 7.0 is regarded as neutral, and pH 7.01 - 14.0 is alkaline. pH (potential of hydrogen) is basically a measurement of how acidic, alkaline, or neutral your water is.

What is the ideal pH for Koi and Goldfish?

Koi and goldfish do best in a pH between 7.0 and 8.6 and most often perish at a level below 6.0. A relatively stable pH of pond water is vital to our pet fish.

For Koi to be healthy, they need a pH in the range of 7.0-8.6, and more importantly they need the pH to remain stable somewhere within in that range. Internally, fish are capable of counteracting pH swings, but only to a degree of a three tenths change per day. Ideally, no change should occur.
