Pond Boss Forums INTRO Questions & Observations Why is My Pond Water Green??

wht89lx - Once you provide the correct info we now know why the water is green. Most of the nutrients are coming from decompostion of dead fish. Ssome of the fish go to the bottom and decay there and do not float.

Ms fisheries biologist is not completely correct in leading you to believe the offspring from the fathead minnows will eat the phytoplankton bloom. The fathead fry will for a few days eat the unicellular and some colonial planktonic algae but they quickly switch to eating rotifers and small crustaceans. Once the get to 1" -1.5" they are thiving on larger crustaceans and small invertebrates. The zooplankton (protozoans, rotifers, and crustaceans) are the primary grazers of the phytoplankton.
