Could this harm my fish?

[Grits]

Is there anyway at ALL that this product could hurt my fish? or Just not be good for them?

NUTRAFIN Plant Gro Fertilizer, 8 oz. (Freshwater Aquarium Supplies > Plant Care/ Fertilizers > Liquid )

Thanks!

You'd have to severely overdose that fertilizer in order to harm your fish. On the otherhand there are other much better trace fertilizers available. I'd recommend that you look at Flourish "Comprehensive", Tropica Plant Nutrition, or CSM+B instead.

It shouldn't, I know a couple people that use that, one goes far enough to risk it in with her monsters and pricy fishes so I would assume that it won't have a negative effect on the fish, though it could be negative for inverts since it has copper in it, but that is a very small amount of copper.

Oops, Purrbox types faster than me! lol
I too agree, if you can find a local hydroponics store, that would be far better than wasting cash on commercial liquids.
