I have 3/4 acre pond, 6 ft avg depth, 10 ft max depth, with aerator 24/7. I have had a HEAVY chara infestation all summer. I just added 8 triploid GC from Overton last month. I know over time they will get this stuff under control, but since they slow down eating in cool water, and not sure if the chara will, should I help them along. I did not chemically treat during the summer due to our high air/water temps (air=95+, water 89+) and fear of hurting fish. The secchi reading exceeds 4 ft (then and now) and I can still see LOTS of chara coming from 8-10 ft areas.

Since the water will start to cool, and fish activity of all kinds should slow, would you recommend a true chemical control, or aqua-shade to filter the light and slow/stop chara spread. I would like to get an algae bloom next spring and have 18" visibility for good fish production. I feed about 3 lbs aquamax/day and have lots of fish, but still get super clear water.

Water temp last night = 72F, LMB and HSB fed aggressively.

Thanks,

Darryl
