So I finally did some tests last night:
Ca - 350
Alk - 10.5
Mg - 1500!
I haven't dosed Mg in ages so Reef Crystals must be high or I need a new kit. Since RC is for sure high in Ca the reduced water changes seems to have lead to a lowered Ca level which I think (I'm not a chemistry guy) means that the corals can't use Alk so the previously acceptable dose was more than needed.
I'm actually sorta stoked with these findings... maybe once I get them back in line growth will return to where it was before.

Nothing more unsightly than HA. I've gone through it before and I've finally learned to calm down, be patient and do what you can.
