| Test to reduce pond foam Ever since my GH dropped down to 4dH, foam has been accumulating on the surface of the pond. I have been using a pool net to scoop some of this out of the pond. I have decided to increase my water and filter maintenance. In the past I have cleaned and backwashed all three filters once a week and replaced 12% water (1,000 gallons). I propose to increase the frequency of filter backwashes to each day and replace 300 gallons per day of pond water or an additional 1500 gallons per week, giving me a grand total of 2500 gallon water changes (30%). I hope the foam accumulation will go away. I will monitor temp/ph/orp/gh/kh for any change from normal.
Any predictions?
