Greenish Tint!
I would appreciate advice on how to eliminate the green tint in my pond
water. The water is "clear" in the sense that I can see the bottom but the green tint, which I assume is algae related, is not good. My system consists of the following: - A 4000 gallon concrete pond (with black epoxy coating) ranging in depth from 3 to 4 feet. We currently have about 15 large koi plus many fingerlings from recent spawns. - A re-circulation system that includes a 36 watt UV light and a large Cyprio filter (18 brushes and 12 foam filter blocks). I clean the brushes and foam blocks each week. - The pond is in full sun much of the afternoon; but, about 35% of the surface is covered by waterlilies. - I treat the pond water according to the directions with "BZT Aquaculture" which is a brand of "microencapsulated bacteria & enzymes."
