I recently enlarged my tank to about 1.5 acres - presently it does not have any grass on the banks or dam area (I'm working on that) and the water is muddy. I did the gypsum test and it seems to clear up nicely with a very small amount of gypsum.
I have noticed a strange green color (almost like green dye on an area about 20 ft long and 10 ft wide along the bank - if seems to follow the wind. Then just yesterday it seemed to have totally disappeared. Now this AM it is back.
Does anyone know what this could be?? I took a stick to see if it had any substance to it but it just seems to be a green liquid floating on the muddy water - strange looking!!
