Pond Boss Forums INTRO Questions & Observations Corn meal

Some local south Texas Gardening experts have been reporting that whole ground corn meal has been very effective with most types of algae in tanks (ponds). Just checkin to see if anyone has had experience with this? Also was curious because some have said that copper sulfate or chelated copper sulfate only works in the short term. I have been using the chelated copper sulfate and have seen some results of course , but still have some algae (filementious mainly). I have stocked the grass carp at six per acre and I suppose they are doing their job, but I understand they go after filementious algae last. Thanks for the forum guys.

I have tried cornmeal in a 1/4 acre pond and had good results early in the Spring before I discontinued use. I believe the stuff works like barley straw in that it harbors particular types of bacteria that seem to tie up phorphorous in the water column. My only concern is the application mess, the availability, cost, and addition of organic matter.

I would consider a microbial agent, combined with limited amounts of barley rolls around the shoreline for a long term control. Good luck!

Thx over, I will try a small quantity and I have used the copper sulfates, but will monitor both.
