Does your pond get a lot of direct sunlight during the day? If so, how many hours/day and how much of the pond gets the full sun? Are there any pond plants in there? Plants such as lilies, water hyacinth, and water lettuce can help a lot with creating cover/protection for the fish and also to block sunlight, plus they help to use up excessive nutrient levels that feed algae blooms.
With this being spring I would also check to see if there are a lot of leaves and other types of natural organic debris in the pond from the fall season... all of the things that blow into the pond during fall will slowly break down and add to the excessive nutrients that contribute to algae blooms.

Does your pond have a filter? If so what type? Is there carbon in the filter?
Can you post any photos of the pond and any filter you are using in it?

The more information you can provide the faster we can help you to sort out what the problem is and get it resolved in a safe way.
Thanks for getting back with me! I will send pics as soon as I can. Our pond is under screen, next to our pool. Unfortunately there is a bit of run off from a near-by pan roof. The pond gets a lot of sun for approx 5-6 hours here in Fl. We have tested water, it is Ok. We do not have any plants in it, or an algae eater fish, but we plan on getting these within the next 2-3 days. We have a pond filter w/ integreated UV-C unit as well as a new pump on the bottom. I noticed there seems to be some pollen on our other outside plants and on the pool deck. We backwashed the filter today taking out 20 gallons until filter ran clear again. I am still leary about how many times these fish are being fed. Does morning noon & night sound right to you? My husband and I disagree on this. I think it is too much. Any input would be appreciated!!l
