PH levels
Question:
I cannot keep my PH at a decent level. It is always at 9.0. I use PH down but that does not seem to help.
Answer:
It sounds like something in the pond is leaching into the water raising the pH (maybe lime stone?). It may be better to use a buffer/stabilizer which will attempt to set the pH to neutral. Try Microbe-Lift Buffer/Stabilizer.
