Different strokes for different folks. Sparkplug has it right. However don't entirely discount the dye. I use Aquashade in ponds that are artificially fed and the ponds are unisex in that there is no spawning wanted or needed. This is primarily my largest grow out pond of female yellow perch and male bluegill. There are pellet feed smallmouth in the pond but they don't reproduce well in the pond and will be reproduced elsewhere.

The dye keeps the macrophytes and phytoplankton down that could get out of hand due to the heavy feeding.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
