In the future i'll be buying a QT tank prior to buying fish. But for now, would it hurt my tank to lower salinity? I have cc for substrate, and 70 lbs of lr, and wet/dry filter. Comments? Suggestions? I really hope i dont lose my trigger, he's got such a cool personality. And the blue devil damsel i have looks even more beautiful then when i first bought him, lol. Those are the only two fish i have alive now.
Your LFS recomended copper? Is your LR still Live? You can't do hypo with any live rock or inverts in your tank. These need to be removed. If the ich was in your display, you need to remove all of your inverts including rock to a temporary tank. After they are all removed bring the salinity of your tank down to 1.009 in the course of 48 hrs. After there are no signs of ich left, count 3 weeks to be sure ich is gone. If you have nowhere to move your rock and inverts to, you will need a reef safe treatment. There is alot of controversy on this site as to how well they work. Stop parasite is a good one, but does not work for everyone. Hypo is the best way to go. You will need a refractometer to be certain of correct readings. Another option, being you only have two fish left is to move them to another tank and let your display run without fish for 6 weeks. Good luck with everything!
