From Fatman:\n\nQuote: - For hyposalinity treatment you would have to slowly lower your tanks specific gravity to 1.011 to 1.012. This is normally done in a seperate tank to only the effected fish and for a period of three to four weeks. If that can not be done then it can be done in your main tank with out harm to the fish as long as the lowering of the salinity is done over a period of hours, or even better over a period of several days, instead of over a period of minutes. - End Quote.\n\nI didn't want to steal a thread, so I am starting up a new one. I know this has been discussed before as I already searched Living Reef and the web to see what I could find out about it. \n\nI am currently using Hypo for a Singapore Angel. I have the DT down to 1.010 - 1.011 and all three fish seem to have adjusted well. The level was brought down over a two day period. I do not have any corals yet. I have read it takes up to eight weeks to be certain that all parasites are gone so I will wait until August to start adding corals. \n\nI would love to hear from individuals who have used this method, both the good and the bad. Is there anything to watch for while using Hypo? The fish seem to be doing great and I want to completely irradicate the problem. All the fish have been in the tank for over four months, the Singapore for six months, without any sign of parasites. \n\nThanks.
