I posted a week or so ago that I bought this product to try on my 75gal reef (with SPS, LPS and softies).
Used the product for 4 days and none of the corals were affected. Bad news is that I saw NO improvement with my fish (who all had varying degrees of mild ICH)
Even worse new is that I lost one of mated pairs of Percs this morning and my Desjardin Tang looks like it probably wont make it to Monday.
the NO-ICH PRODUCT had no side-effect on my corals yet seem to make my ICH problem WORSE shortly after discontinuing the product.
