has anyone tried this....
 

has anyone tried this product for ick in a reef tank..protomarin coral...if so how did it work for you...

Didn't do a thing for me. Used it on a minor outbreak, no luck. Pretty much a waste of money for me. I have better luck with daily feedings soaked in Selcon and Garlic.

One good medication that worked for me was No sick fish Ich medication, and it is reef safe. I've used it with great success on my tangs and no loss of snails, crabs, shrimps, or any of my sps, lps, ployps etc. The best part is I have not had another outbreak since I used it. The price tag is a little hefty, (I paid $40 for one treatment -7 days-) but well worth it.
