We purchased a hippo tang and on day 3 noted white spot on side of her. Started treating with this product right away at the 1.5 multiple treatment rate. Treated the DT once per day. Also added a UV
sterilizer to try and reduce the number of free floaters once they hit that part of their life cycle. I lost 2 fish during the outbreak and also (maybe not related but) lost a BTA. As I started dosing, it starting shrinking up until it was gone. All other water parameters were fine at that time and all other corals were unaffected.
For me, with the research I did and the comments posted from other forum members, I accept the fact that I still have ich in my DT. It can only be eliminated if the tank if fish free for 8 weeks or so. I believe that this treatment was the best option I had for my reef tank. I have been over 10 weeks without another outbreak. I would recommend it as part of an overall treatment plan.
