How about some pics? Half full, almost full? I had major work done on a 2 acre pond last Aug and it was hot (low pH) and was kinda clear.
1/2 full pH hella off w some sediment but clear with little or no microbe growth.
Pond full, pH getting there and lots of microbe growth limiting the visibility. I believe I have suspended sediment as well and with help here I found out about Ag Gypsum as an amendment that I will apply to add Ca, attach to suspended sediment and drop to the bottom, it will also amend the pH a little. That info's down in pond water chemistry thread.
What's causing your visibility occlusion is the key.
