A couple days ago i noticed a couple of my tangs started to get ich. I asked around and some people mentioned using prazi pro in my DT. I was wonder if anyone has done this before and if so what should i expect. I know that the prazi will kill off any bristleworm, snails, and shrimp but will it affect any corals or affect my DT in the future when it comes to adding more inverts and corals. any help/tips would be greatly appreciated Thank you!
