algae can't grow without sunlight, so shading the troughs is the easiest maintenance free way. in my pool, I use chlorine tablets which has a chlorine stabilizer, and I never had a problem all summer with algae. in my pond, I use a UV sterilizer light, which gets fed by the waterfall pump. that works too, but then you have to have a pump system along with the sterilizer light, which gets plumbed into the pump..
