.3 ppm copper levels

My levels aren't going up and aren't going down. I was told to add more carbon to the filters and that will help drop them. Is this a safe level for invertebrates without becoming toxic. I have a 55 gal FOWLR tank.

Heres an article on Copper treatment levels in an aquarium. They mention levels in 0.15-0.2 mg/l. I'm not sure what the conversion factor is as the Cu molecule is much heavier than water, so it would likely be less than .15-.2 ppm. To remoce copper they also say you need 1 lb of activated charcoal per 50 gal to remove said dose.

You can try carbon but as I stated before you may never be able to add inverts. If its in the rocks and silicon you may never get rid of it.
