I've been away for work the last 6 months and I didn't get to work with my pond so now I have hydrilla growing to the surface even in the 12' deep water in my 1 acre pond. Water is as clear as a pool, hard to catch bass, only have rain run off does the water get a little dingy and I can catch them for a little while. I am in South Louisiana, still 80 degrees, and I will use chemicals to start killing off some of the hydrilla, too much habitat, fish are everywhere. Water is still 80 degrees, can I pour liquid fertilizer and expect an algae bloom this late in the year? Thank you in advance!
