Alright, I'm currently looking into dosing my aquarium, most products I see say do not use with inverts. I currently have a 30g with a few nassarius, ceriths, and astraea snails along with a 2 hermits and an emerald crab and 2 cleaner shrimp. The coral I have are a Purple Stylo, Green Duncan, and GSP. I'm just wondering if it's something that's possible, but err on the side of caution, don't bother dosing, or are the coral I own atm not need dosing?
