...another idea to very slowly and incrementally add dye (well below normal dosages) over a 10 to 20 day period to slowly kill the thick plankton bloom and ward off a plankton or vegetation die off and O2 crash (should we get a cold front or something). his recommendation was to maintain the aeration schedule as is and dont artificially cause large temperature shifts (which might cause a sudden vegetation/plankton kill).
Another way to look at it is that you're not really slowly killing it off as you are inhibiting reproduction of the phytoplankton.
Phytoplankton is always dying off anyway. Very short life span. But in the case of an increasing phytoplankton bloom, you are getting reproduction more rapidly than individual units die off. If you added the dye really slowly, you're inhibiting reproduction from the bottom up. You'll have a narrower and narrower band of adequate light penetration, so utimately you should be able to reach the tipping point at which your bloom will begin to recede. I'm just nervous about seeing it go all at once when the weather starts to cool.
For some reason I can't seem to find any holes in this idea. It's cheap, easy, and should reduce the possibility of a pond-wide algae crash, which I believe to be the most significant possible cause of a massive fish kill.
