How come your alkalinity is so high? Are you dosing something for alkalinity? what type of salt are you using?
You just have to keep in mind that with very low level of nutriment it is a risk to have RTN or STN when you have such high alkalinity. It is not safe to keep your alkalinity so high.
First step is to raise your magnesium and calcium slowly, but don't dose anything for alkalinity until it drop lower. If you don't have much in coral it may take a while before your current alkalinity level drop.
But before buying any delicate SPS I would get these value: calcium 420, magnesium 1350, alkalinity 8. Then try to keep this stable and you will be fine.
