My pond ( a little more than 1 acre) currently only has 4-6 inches of visibility and hardly any vegetation that I can tell. I am wanting to fertilize my pond but not to sure what type of fertilizer I need, if it is the right time to apply it or if it would even do any good due to the visibility. The pond is located in Texas south of Dallas and I have not measured the temp but I am sure it is over 60 degrees.

Thanks
