I just measured my Mg and learned that it slipped down to 1100 from last month's test & adjustment. The reef chemistry calculator indicates that I need ~85 oz. of Randy's mix. It says that you can add this all at once but I want to be careful. Over what period of time would you spread this out?

If you read Randy's article about Mg, he recommends not raising it more than 100 ppm per day.

I recently had to bump mine up over a couple of days myself. Was a lot more comfortable doing that than just adding a ton of it at once.

3 days and you should be fine, for sure not all at once.

Furn I'd raise it over a couple of days as well.
