Right, typically carbon dosing affects N far more than P. You'll still need lanthanum to reduce if the overall goal is P reduction.Well, lanthanum binds phosphate and this produce likely also removes nitrate
Based on what’s in it I think it’ll be fine to use carefully, but probably won’t be that effective for algae removal. You need herbivores for that
