Two weeks ago, we put 4/5 bottle of Airmax Twilight Blue dye into our pond which had been a light brown stain; Secchi visibility was 15" prior to placing the dye.

One week ago, we checked the pond after some wind and rain and the pond had a nice green color to it, but Secchi visibility was still 15".

Friday evening, Secchi visibility was about 24" following a week of mostly hot/dry weather and the aerator running 30/min day in the evenings.

Yesterday, one day later, Secchi visibility was 28-30". My 7 year old also took his birthday present Ryobi trimmer out to knock down some tall grass close to the pond where I can't get my Fastrak.

I also ordered another Moultree directional feeder and more Optimal, this time Bluegill instead of Junior.
