Maybe they have only a small amount of the agent that captures heavy metals, which

the levels ?


I got this response from Seachem:

Prime will bind heavy metals from solution when you are treating new
water. In a plant tank the impact would actually be beneficial as it
would reduce any iron from a ferric form to a ferrous form which the
plants are able to use more readily. Prime is fine to use in a plant
tank and as far as the iron goes it would be helpful to the plants.
