Here's another testimonial for what DOES work in a reef tank!!
There's been an ongoing debate regarding any product that actually does work to kill ick in a reef tank.... I had ick break out and I tried a couple of products with no results, then I tried catching the fish and quarantining them, (what an ordeal and I couldnt catch one of them even after tearing the whole thing apart)
SO.. I decided to order and try the one product the debate was about... Chem Marine Stop Parasite.... well guess what? It came in Monday and I started using it and here it is Thursday and the ick is almost completely gone already! It really does work!!!
Give it a try!!
