Seriously does any one have a reef safe cure for ich. Years ago I used to use formaldehyde for ich in a reef tank and it worked. It stressed out the corals a little but did not kill them. Only enough was used to kill the ich. I also used it to treat marine velvet with success. The trick is to use the right amount. Unfortunately I don't remember the ratio. I hate watching my fish croak helplessly.
