Pond developed a leak which was fixed in October 2014. Great water color at that time which was about 2 feet low. While pond was low I added about 20 green Christmas trees. Pond refilled in January 2015 and has been a coffee color ever since. About March 2015 noticed a black tint in water that will scatter when a bait hits the water or a fish moves. Haven't seen any dead fish or odors. Prior to this the water color has been really good. Any ideas?
Went out to pond today. Water is still a coffee color and the black stuff in the glass still blows with the wind like a black cloud. I'm at a loss. The fish seem to be doing fine. Haven't seen any floaters.
Stir in some baking soda and see if it clumps and settles out.
I have found every time I put even one Christmas tree in when the water gets to 65-70 I get a alga bloom. I only have been putting one in a year or so no more then that. I have about a million gallons in my pond.
