I have been keeping koi since 2006. I had issues with algae in the spring but I always managed to take care of the problem. I am wondering if someone has come up with "an invention" to move all floating dead algae to the skimmer. I treat with PP with no issues but the dead algae have to be removed from the pond. I use hydrogen peroxide as a preventer of algae attacks but still, in the middle of the afternoon, any dead algae at the bottom will come to the surface and then "we" have to use a net to remove floating dead algae. There has got to be an invention that someone has created whereby a temporary flush of surface algae can be directed toward the skimmer. Any such invention yet
?
