I have a ich problem,and need the corals out for the salinity drop.The tank will be at 1.009 for 6 weeks,and any live rock that is taken out will have to wait 12 weeks before putting back in tank.My sand bed will die off,so I will get about 20 lbs out to seed back when done hypo.Some corals will go in my 28,I will start moveing things out today.I will never put another fish or coral without qt it.
