With all of the chemicals, aren't you just adding to the organic muck base on the pond bottom? As the sludge decomposes, the nutrients are re-released and then more chemicals, more expensive chemicals, more frequent treatrments, etc...
Also, what about your aerobic bacteria. The chemicals kil that as well and then you may have to add more aerobic bacteria IF you have any DO2 at the bottom.
I think better to remove as much of the algae as possible which also reduces the nutrients in the pond and work to change the pond from algae based to rooted plant based to take up the nutrients. Many ways to harvest the algae now.
