What is the ideal pH range for my water garden?
Goldfish, koi and golden orfe prefer a range of 6.5 to 7.5 for ideal water conditions. This measure of alkalinity or acidity is important because the proper pH determines how well the beneficial bacteria contribute to breakdown of organic waste in the water garden. Too high or too low pH values slow the rate of bacterial activity that can also cause a build up of ammonia, nitrates, and even green water.
