I believe there's something in Kent's as many people have been suspecting that this mystery ingredient can kill the bryopsis algae, not other magnesium products.

Using it? I am, so I would agree.

I might be a bit more conservative than what you're suggesting in raising the daily mag levels, though.

Mexican Turbo Snails have been reported to be sensitive to it. At 1600 ppm someone, somewhere, reported that his Mexicans were no longer "sticky" when they were napping: they'd fall of the glass and rocks. I believe long spine urchins were also indicated as being sensitive. I don't remember the details.

You might like to ensure that you hit 1600 ppm on the first of your days off, so you can monitor the effects and do a wc if nessecary.

Thanks for that Shelley

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 :redface:
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
