What is your Calcium at?

Calcium is at 360, and I have been using brightwell aquatics magnisium. 100ml per day for a 220 gallon tank.

You might want to try bumping them in tandem, although dosing on alternating days. However, if you are happy with your Ca. level, I'm not sure what to recommend to you. I usually bump/maintain my Mg. levels with a Mag. additive in my Ca. reactor, or I used to dose mag cystals from Little Silver Max. I have never used a Brightwell product, so I don't have any hands on experience with their stuff.

Thanks for the advise,

By using one of these reef calculators you will get a better idea of the dosage necessary to bring your levels up to your desired level.

I've been using Mag from LSM for about a year and it works great. I figured out how much my Mag, Cal, and Alk go down per day and dose accordingly. In my case I had to overdose quite a bit to get levels up. Now maintaining with daily dosing is easy.

Is it odd for it to be so low? I had been using instant ocean salt, but have recently switched to reef crystals. The tank is only 6 months old.

i tried everything to get my levels up at one time.. I find liquid additives dont work well.. Then I tried the reefchem mag flakes.. wow.. brought it up very well over a couple days.. I use this now in my new IO salt for water changes..

I too have had problems increasing Mg and Ca levels. I have been using liquid supplements but that has become expensive. I have been using Reef Crystals but have not been impressed. I have tested new salt water mixes at 1.026 sg (using refractometer) and got readings of 360 ppm Ca and 980 ppm Mg using two different brand test kits. I will be switching to a new salt.
