jest trying to varify Mg levels it was 1020 with a 13 month old salifert test kit

I just got 1250 from my newest bucket.

I just tested with a new Seachem test kit and got 1000 at 1.026

At 1.026 IO should read about 1200-1250 on a Salifert.

Really, 1200-1250 at 1.026, I thought it ran a litlle lower than that

What are you guys using to boost mg?

 

[DrBDC]

I usually boost it about 150 before adding and that puts me right about 1350. I use MgCl/epsom salts as in Randy's homemade 2 part for the boost. I boost the ca from about 380-420.

I have used ESV's product and Kent Tech-M. Any product with a high ratio of magnesium chloride is fine. There's also a DIY recipe available.

For a one-time shot, Epsom salt is likely okay.

So how much epsom would I add for say 10g of IO water?

That calculator should do the trick. You didn't list the current magnesium level, but the web page is very easy to use.
