Pond Boss Forums MANAGING AN EXISTING POND Fertilization Green film after fertlization

I have a green film appear on the surface after I fertlized the pond. I have a 3/4 acre pond. Help!!!

thats normal, if you cant stand it consider an aerator that really moves the surface of the water. moving the water will make it look better. check your visibility, if its 12-18 inches consider backing off some on the fertilizer. add 1/2 as much an see what happens, you can always add more. try to keep visibility around 18-24, you will like the appearance of the pond much better and fish seem to bite a bit better. I think because they can see better

I think there is something to that seeing thing. When my fertilizer finally took hold after the 3rd application my visibility went down to about 10 inches and maybe even less for a few days. I had started a feeding program and fewer fish began showing up until they almost stopped. After the rains we had a week or so back, my visibility is back around 2.5 feet and fish began hitting the food immediately after that. I've still got my time release floating bucket of southern excellence recommended by PondBoss in there but so far with no rain for the past 9 days, no bloom has returned. I do have very slight red particle like film in spots on the pond now. And in places it looks like dirty soap bubbles. Not sure that that is myself. But the fish are still eating the feed good with such high visibility.

the red spots are a form of microscopic algae, I see it about once per year. you can treat with copper but it tends to return. cant think of a situation that it caused problems
