Which skimmer are you using ? How close is the powerheads to the surface ? What is the size of the tank ? How many fish do you have ? How often are you feeding ?

I have made several water changes in the last few days, probably more than I should, but the nitrate doesn't seem to have moved from the 160

Which test kit are you using ? How large have been the water changes ? You say you've made more W/C's than you should've, did you match temp., salt mix and SG ? If so then there shouldn't be a problem as large W/C's are what's necessary to bring these down short term.
