Default Magnesium magically stable (and high)

I haven't dosed mag to the tank since the transfer. I dose roughly 250mL of Ca/Alk per day.

I thought my Elos kit was off with a 1500 reading yesterday so I cracked into a new one and got the same thing! How is this possible?

Not sure it's related but coral growth is great and most of my coraline has died. New coraline forms on the glass extremely slowly.

Reef Crystals.

I also don't test my new water but maybe I should for fun. No way it's that high tho. I test the tank a day later and adjust if needed. Only minor adjustments are ever needed and I'm sure more due to corals using more of my money up.

I was running about 1500+ mg in my tank for a while, too. I never dose mg, but I dose Seachem Reef Advantage Calcium which adds mg along with the ca. I was also using Royal Nature salt for a time which I think had more mg in it. Lately I have been using just the cheap Instant Ocean salt, and my mg is now running around a more normal 1200.

Solutions are easy. The real difficulty lies in discovering the problem.

I'm pretty sure Instant Ocean's Mg levels are up lately, perhaps Reef Crystals is as well.

Cool! I would imagine it's your salt and you seem to be pretty diligent with waterchanges. Test your incoming and see what it's at, I bet that's why.

Tested my Mg last night and got 1450 with Elos. Tank has been running for a little over 1 1/2 months with no supplemented Mg, all IO salt.

Crazy seems like a common problem. I know when mag is low it can be tough to balance the other two but it seems to have no effect being at 1500 (normally I aimed for 1400). I can't bring it down anyways but I am going to test my next wc out of curiosity and I'll post back.

Maybe Elos sucks consistently too!

Tested tonight on a fresh bucket of IO, didn't take the time to roll it or whatever i was supposed to do to mix it.

Mg: 840 ppm
Alk: 10.4 dkH
Ca: 320 ppm

Guess I'm continuing to dose magnesium

Just did my wc today and forgot to test oops! That's crazy low christy and it takes a lot of supplements to raise mag that much.
