Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Stocking Tilapia for FA

Not being a smart a.. but what does the label say?

FWIW, AQUATIC USES:
Waters treated with this product may be hazardous to aquatic organisms. Treatment of aquatic
weeds and algae can result in oxygen loss from decomposition of dead biomass. This oxygen loss
can cause fish and invertebrate suffocation. To minimize this hazard, do not treat more than 1/2 of
the water body (excluding water infrastructure and constructed conveyances such as drainage
canals, ditches and pipelines or intakes and aqueducts for drinking water or irrigation use) to avoid
depletion of oxygen due to decaying vegetation. Wait at least 14 days between treatments.

Dye *might* kill some FA, depending on how dense you dye it and the water clarity now. Check with a secchi disc pre/post application. Plants/algae can grow 18"-24" deeper than the secchi disc reading. If I am not feeding the fish in the pond, I don't like to use dye.

If there are underwater plants in the pond, killing the algae and dye *could* kill some of the plants due to the increased phytoplankton bloom after the FA is gone, because of less light penetration, and dye will make that worse. Like we say here, "It all depends" (on multiple factors).
