Just figured out why my neighbor's koi pond never goes green and mine turns to pea soup by July
Was out refilling my pond in the backyard last Saturday and my neighbor Dave across the fence mentioned he has not cleaned his filter pads since April, which made zero sense to me because his water stays clear while mine turns green every summer. Turns out he keeps his pond at about 60% shade all day with a big maple while mine sits in full sun from 10am to 6pm, and that shade is doing more for him than any filter ever did for me. Now I am looking at moving my whole setup or building some kind of shade sail, but I am worried the leaves in fall will be a nightmare. Anyone here gone the shade route and regretted it?
