Cleaning a Natural Pond

How to clean a natural pond?
We have just bought a piece of property with a pond on it, I don't know the depth yet but we are planning to use our inflatable fishing boat to try get an idea on the depth. There are cat tail plants growing around the edge and algae on the surface near the edges. There are also fish in the pond though we don't know what kind, we only know they're there because we saw them come up and splash after bugs that were on the surface. We want the pond to look nice and continue to have fish in it. What is our first step? Just digging out the cat tails are skimming off the algae? What else do you recommend? We've heard about blue dyes and probiotics are these some things we should be looking in to?

Answer:

You can remove some of the cattails, but I would not remove them all by any means. The pond looks healthy now, so proceed with care. I would use no algaecides or any other chemicals. You could put some barley straw in to take care of some of the algae, but it usually disappears on its own.
There are enzymes and bacteria you can introduce to the pond, but I would use only barley straw for now. After you have been there for awhile and gotten to know your pond, then consider dyes or probiotics.
The cat tails are providing valuable natural filtration.
Skimming off the existing algae is fine.
