Raising Mg

[Ruth]

I have just started to switch one of my tanks over to the new Seachem reef salt which is supposed to be higher in Mg. - I will test it next week when I mix up a batch. The other thing I have heard of but have never tried is to run some - I believe it is dolomite - in your calcium reactor to maintain mg.

In past years, before reactors, I always used ESV magnesium with good success. When I started to run a reactor with ARM media, the level was always around 1350ppm.

I dont run a reactor anymore. I now add a magnesium product to any new batch of saltwater. Plus a spoon of calcium, to bring it up to proper levels.
