I'm assuming this is what this is a picture of. Beings that I am a pond rookie, this is the first time i've ever seen this.

That is indeed a plankton bloom. Very strong bloom. Did you fertilize ?

no sir I didn't. Water is still quite muddy from filling up. Is a "very strong bloom" a good or bad thing???

Don't usually see a plankton bloom in a muddy pond. If you stick your hand in the water - how far down in the water does your hand go before you can't see it ? If 18 inches (elbow) you are ok. You don't want it to get less than 12 inches.
Phytoplankton
form the base of the food
chain and are eaten by small
animal organisms, which
serve as food for bream,
which in turn are eaten by
bass. Phytoplankton make
the water turn green, or
“bloom,” which also shades
the bottom and discourages
growth of troublesome
aquatic weeds.
Although the plankton blooms
that result from fertilization can
be highly desirable, too much
bloom can cause problems. Dense
plankton blooms (Secchi disk visibility
<12 inches) can lead to: 1)
plankton die-offs that deplete dissolved
oxygen; 2) critically lower
dissolved oxygen readings in the
morning; and 3) elevated after-
noon pH levels which increase the
concentration of unionized (toxic)
ammonia in the water. All of these
conditions can stress fish. In some
cases, dense algae blooms even
produce toxins.

not at the house now but it is definately less than 12 inches. Probably more like 6 inches. I defiantely need some gypsum to help clear it. I did the jar test and gypsum worked great. My only concern with the gypsum is the amount of silt that will settle to the bottom. Pond is only around 8' at the deepest. Pond is all excavated. Here is another picture of the water taken at the same time. The water is green only in some areas.

Keith, do some research on alum to clear up your pond, it's a lot more effective, just watch your PH levels. I had the same problem. I put 2 50 lb. bags directly into the water via paddling around in a jon boat, and placed 6 more where the major runoff channel entered the 2 acre pond. It lasted 2 years and muddy water was history.

Right now in Western Central Arkansas we're having severe pollen from trees. Green dust is everywhere thick and even makes the water look green. Could that just be pollen on your pond?

It's possible but I seriously doubt it. Earlier in the year I definately had pollen in the pond but this looks totally different.

mine is more muddy with green areas. This is what the pond looked like a few months ago so I guess today it does have somewhat of a green tint to it. Maybe I'm just being optomistic.
