To be honest I haven't adjusted my water. I found the reef crystals levels are great and consistent. I just made sure when figuring out my daily doses to test levels a week apart a day after my weekly water change both times. I thought this way whatever my water change params are (i know they're really good anyways) they are accounted for in my daily dose.

As far as SG...drops from 1.025 to 1.024 by the end of the week usually and I mix my fresh stuff to 1.026 and so far so good it's all been balancing out.

Tony what salt are you using? my reef crystals test just a touch high for ca, and ideal for dkh and mg.

I've never really tested. My salinity seems consistent all the time at 1.026 even when I dump in 1/2 kg of Mg at once. Interesting to not though.

I generally add 1 cup of mg salt (magnesium sulfate + magnesium chloride) to 27gal of RO water and then enough aquarium salt (about 6 cups) to bring it up to 1.025.

Is there any temp change from when you test the salinity before and after you add the mag? I didn't think mag had any affect on salinity. Maybe mix up a batch of ro water and add mag to it and see if the salinity changes (salt in your mag)?
