I get asked about pond dye a lot and I really do like the stuff.
I don't necessarily ever recommend it above aeration, beneficial bacteria, or even chemicals in some cases because pond dye may not be powerful enough to turn a pond or weed problem around.
But it can surely slow them down or help these other methods work better.
Plus it's safe...made out of non-toxic, food grade ingredients, it's an eco-friendly way to help.
