Super low mag?

[Mattj815]

So until recently I rarely tested magnesium. Ive been reading some more lately and decided to make it a point to test more often.

As of a few days ago I was showing around 600. Ive read of innacurate tests but got it twice on salifert kit. So I went out and bought brightwells mag supplement. I started slow, 15 ml the first day and 10 the day after that.

I just tested again and was around 1100. My calc and alk are good at 420 and 8.3. Should I get a different kit to confirm? Is it possible for my tank to just be rating thru mag like this? Ive read that some signs are no coralline which I barely have and some corals receding. My torches arent what they used to be. Most stuff is ok.

Cant keep and sps or a chalice for the life of me.

Should I keep dosing until my salifert kit reads ok?

I rely on salifert hands down. sounds like you simply have low magnesium. I would first suspect the salt, what brand of salt are you using for water changes?

I trust salifert mag test ...if you've never tested for mag it is possible it went that low and could explain your corals.. I would keep adding and testing and maybe get a sample of water too lfs and let them check as well ..just for a second opinion ....

Depending on how much and how often you do a wc and how many corals you have ...you might not be replenishing it , even with red sea pro ..are you dosing calc alk mag .?

I do a wc about every week and a half to two weeks. I have a decent amount of coral in a 40 cube I guess. Most lps and softies.

I dont dose anything except kalk and as of very recently, mag. Ive been looking into 2 part was trying to decide if I needed it.

I was getting poor results with api alk kit. So bought a Hanna alk tester and my alk has been good ever since using that.

You can raise mag 100ppm safely per day , I like too keep mine around 1400 ...and often dose 75-100ml Triton mag in one go ...
