Got it. Thanks. Are there any ich medications you would recommend that are invert safe? What about invert and coral safe?
There are not any true ich medications that are invertebrate safe - killing a protozoan is just too similar to killing an invertebrate/coral. There is a LOT of snake oil out there, being sold as "reef safe", but most do not work, and those that do, only work in light cases. Polyp Lab Medic probably has the best real science behind it for a "reef safe" medication.
