Dosing alk and mag?

[williamCreery]

I'd double-check those calculations - that seems like a f**k ton of magnesium. Unless you have an insanely big tank...

Opposite for me. I run 1300-1400 magnesium. On the 20Gallon
1200 max Mag for the 240Gal

Why not use all.for reef? No effect on ph and keeps alk rock solid. Has mag in it

Yes please use the BRS calculator.

If you’re short, you can go about 150ml MAX a day on magnesium. To be in the safe zone.
EXAMPLE: One dose of 150ml Friday… one dose of 150ml Monday Magnesium.
EXAMPLE Alkalinity: one dose of BRS amount. One Friday of ml and one dose on Monday ml.

Yes, the local rise is going to be much more than in the display.

You can dose large amounts of magnesium at a time imo.

Somebody was telling me today that nobody should be dosing mag? And if i dose mag to lift from 1260 to 1350 it will casue dilution?

Because i got a bad batch of salt, and the calcium ia 420, mag and alk is bad.

Why someone would say that I have no clue. I think you can easily dose 90-100ppm like that at once with no issue. I've dosed cupfulls at a time.

Have you double checked that its not a test kit issue?

Calcium 420 is on the low end. Bring that up too. Like i said all for reef does em all plus traces

A bad batch is salt is orders of magnitude less common than bad test results.

It is easy to dose and I have DIY recipes (BRS uses them), but you might be referring to me, when I have said that, IMO, it is questionable whether folks should ever bother to test magnesium. Bad rest results are very common and true magnesium problems that are not simply salinity issues are quite uncommon.

If you use an alk and calcium method that adds a reasonable amount of magnesium, then IMO, testing magnesium is more trouble than it is worth.
