Kent Tech M Magnesium - please check my math

[Madreefer]

The only thing that I know of that the Kent Mg works on is bryopsis. I used it for that and it worked good but required a huge amount. To maintain my Mg I use a mixture of Epsom salts and Absolute Zero driveway ice melting salt. It's a really cheap way to go about it. And the reef calculator is usually bang on with it's calculations so I don't know why you don't like using it

I'll have another look at the calculator
Last time I tried to use it, something didn't make sense
Might have just been a brain fart

Sooooo ....
Completely different calculator there
I can't even find the one that I didn't like

I'll have to try this one later though as it won't finish loading right now
