Pond Boss Forums MANAGING AN EXISTING POND Fertilization Too Much Bloom

Depending upon the degree of bloom (plankton or blue-green), you might consider reducing (but NOT severely crashing) the bloom with very low-dose sequential treatments of a chelated copper to limited areas of the pond. I've observed this tactic's successful in larger lakes (30-100 acres). BUT, I can't assure you that the use (or avoidance) of this tactic will avoid a DO problem. It is simply a concept for implementing a "controlled" algae reduction rather than allowing a potential weather-event to crash the population (and DO) in one fell swoop.
