Sounds reasonable to me.All my sps I’ve had since tiny frags. I manually dose all my major and minor elements. When I test and alk gets low I’ll increase alk by 1.4 dkh in a day. That is what Red Sea said was the limit in their dosing manual. I was new and I didn’t no otherwise. Been doing that since I’ve had sps(like 10 months) and they’ve done nothing but grow like maniacs. Ain’t nobody killin sps with a little alk jump lol. I’ve learned to dose a lol each day based on consumption for “stability” reasons but even then it’s drinking .4 a day technically that’s a .4 swing per day right?
