Pond Boss Forums GENERAL QUESTIONS Muddy water Dog and muddy water

If the pond stays muddy, and it's a colloidal imbalance that is causing the clay to stay suspended, the dog swimming will be a good indicator of when you need to retreat. If enough alum is used, there will be enough to keep the clay from becoming suspended for a while. Make sure to buffer it with 50% hydrated lime to prevent a large pH swing and a possible fish kill.
