Alk is 9.0. I’ve been getting awesome growth lately dosing trace elements but at the same time my coralline has been taking off. I believe this caused my magnesium dropped to 1200 so I’ve started dosing BRS mag mix 300 ml daily to get that up. Which has also slightly raised my salinity from 1.025 to a little over 1.026 nearing 1.027. So maybe it is a combination of a little of everything.
