1 acre pond, 1.5 yrs old, max depth 13 feet, CNBG and LMB in NE Tx. Put in bottom aeration system about 6 weeks ago and the algae bloom I had before has been gone ever since (I think) replaced with brown, turbid water. We have had a lot of rain and cloudy days but I have fertilized several times and can't get the water green. What has me confused is the turbidity from the aeration has my visibility down to 15 inches. Do I keep dumping fertilizer until I see green water or hold off since the visibility level is good?
