I thought I would post this becuase some of you gave detailed answers to the pond questions I had.
I removed all the algae blooms with smelt nets first. A friend and I got into my 14 foot alum boat and took it all out. It kinda looked funny I must say because the pond is not huge. Not small either but it did kinda look funny.
Anyway after the algae blooms were cleared away about a hours worth of work we applied "Aquashadow"
I went to a farm store and looked at several possible solutions. The Aquashadow said in multiple places that it would not harm fish but would stop algae. The way it works is it is a dye that colors the water a very nice looking blue. This then creates a layer by which the UV of the sun can not penetrate thus taking away what the algae needs to multiply. It does not however reduce the amount of air in the pond.
I hooked up a air pump and circulated the water for a solid 12 hours to spread evenly and make sure there was adequate air for the fish just in case.
All fish are doing fine, no kill off at all. Algae has not returned.
Went swimming in the crisp new clean water on Sunday night.
It is a bit pricey but well worth it. It cost about $65 with tax. I have enough for 4 treatments at this cost which really brings down the overall cost of ownership. A treatment is to last around 3-4 months.
