Help dosing Brightwell Magnesion-p

[GoFish]

Things went well thanks! After 2 days of dosing 31 grams/day which should have raised it to 1350, it ended up at 1320 which is just fine with me.
I'm only dosing because I slacked on changes (new LED lighting caused an encrusting sps to grow like a weed) my Mag was low as well as Cal at 360 hence the need to dose.

Next step Is calcium, shooting for around 420

10% water change earlier today and again by next weekend

And Greg, lol, I thought that sounded weird... Thanks to google it told me NSW was the real deal
