Hey everyone, looking for some guidance as it's the first time I've ever gone threw this.

About a month ago I picked up a few frags. Starting off I always dip my corals before they go in my dt. They sat on my frag rack for a a few days and looked awesome. I glued them down and they continued to look amazing. The last two weeks one of them started to go downhill. I'm not going to lie and I was having difficulty with stability. I didn't have an ato and my levels were always jumping around. Going threw my notebook I also had a few all swings. I think they were related to both my lack of ato and the addition to so many hard corals using up the ALK in the water. I'm currently sitting at 35ppt, 8dkh, no3 .75, po4 .04-.08, mag 1600(not sure about that one), cal 470. Here are some photos. Starting with older to more recent ones.

I'm still trying to learn and had no idea what STN or RTN even was until this morning. I've turned my lights down 10% and turned my lights from 12 hours to 10. Figured I'd start with that and ask for help and where to go from here.
