Yes, I use Keeton Industries Aquatron for my trout pond. It really cleared it up. I started with suspended algae which it cleared up and then filimentous algae showed up due to the increased clearity. However that didn't last and the water cleared up again. Unfortunately the stuff is really expensive and I wasn't able to order more when I needed it right away. So I'm back to suspended algae but it is not that bad. I look to see the water clear again soon now that I have bought some more.

Points:

1.)It's expensive stuff

2.)It seems to work

3.) Other brands may not work as well or even better(don't know as I haven't done a scientific study with a control)

4.) I need to add more than they suggest probably due to all the nutrients I add to the water (feeding about 300 lbs of trout in a 1/10 acre pond), and I have u to 45 gpms of water flowing through the pond possibly diluting the bacteria).

4.) It seems to take several week to see results

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
