None so far... This is only my second year owning the pond and I fought this problem last year but it didn't come on until a lot later..

Mine when mixed by rain or wind appears to all the same color...The suspended particles move up and down in the water column depending on weather... It has pretty much caused me to drink and lose many hours of sleep...
