ok for the last two week I have been dealing with ich. I was treating with garlic, vit c with no luck. so at my last straw I called up to union. the guys told me that I can use this stuff called CHEM MARIN stop parasites. I figured at this point the fish were going to die from ich. my maroon clown, dotty , and tang had so much that they had become fuzzy. Well with 48 hours you could see the ich coming off in slime coats. It never hurt any of my corals, shrimps, crabs or snails. The only prob;em is watching the PH.you could actually see the dead ich today floating on top of the water. today is day 4 of the treatment and I only lost one fish, everyone looks great. the one fish that I had thought died because she was so covered in ich, and I had not seen her in days. well today she is out swimming. thank god dave has been going through thus every step with me. oh by the way dave I set up the nano cube I hide it between my dresser and my shoe's. I have a 10 foot by 8 foot walk in closet. I don't think my husband will find yet
