Often the label suggestion of treating only 25-33%can be too way much at one time. Diquat will react fast with proper coverage especially if you apply when sunny (do apply with sun in the forecast if possible) and takes Gregs warning on no dye at this time as you will need all the DO you can get if it turns to clouds for several days.Have two fish kills going on now with Crystal Plex and Diquat with lots of aeration because the 1/3 teatment on FA was too much (pond owner applied)D.O. in yesterdays clouds was 2.37 ppm and today 6.65 with lots of sun.USE CAUTION !! and good luck
