Rid pond of algae???

Catfish eat algae and we people eat catfish. Win, win.

I also believe that using some sort of air pump will kill off the algae, not a shop compressor but something more like the output from a vacuum cleaner.
eg; high volume low pressure.

Aeration is the right way to address this. You don't need much for a pond this size. Look on line and you will find lots of suppliers. It's a much healthier solution than chemicals.

I've seen small windmill driven air pumps that accomplish this. They aerate the water, and are also another focal point.
Then again no pond is complete without a few fish.
