Help: SPS bleaching and STN

If you are paying for your water, then you might want to consider a RO unit that is low on water usage like this one, which will waste no water, so cost much less at the end:

If you are using tap water I would start with using RO. This is probably your problem.

Also going to try some BRS GFO in a media bag, in my filter sock. But I'll put it on the output of my protein skimmer.

I really want to get a way from carbon dosing entirely. It's scaring me off.

I am thinking it was a combination of ALK ( initially at 7 and then I slowly raised it to 8), and bad water quality. Lesson learnt, listen to people's advice as they have been there, done that.

Thanks for the link Daniella. That was the main reason why I didn't purchase a RODI in the first place. It just wastes so much water. I'll check out that unit you posted.

If you are running zeovit to lower nutrients then definitely get your dkh down to 7-7.5 and keep it stable there. I started zeovit in my tank 2 months ago and I can say that higher dkh than that you will start noticing burnt tips on some acros which will lead to stn. That's just my experience so I would try to work on lowering your alkalinity.
