that 80+lbs of LR is going to hinder the performance of that UV sterilizer. Also be careful raising your temp. All that does is speed up the life cycle of ich, not necessarily kill it. It could however stress or kill any corals or inverts. If you'd be willing to remove the inverts and corals (if you have any) and put them in another tank, you could lower the salinity of the tank. That method will kill ich. You could also go vice versa and put the tang in another tank where you drop the salinity down to I believe 15ppt (make sure that's correct).
