Very low Mg and Alk

[xenon]

I suspect you may have got the reagents mixed up because those numbers make no sense.

The LFS currently has a sample of my tank water, so far they have also found the Alk to virtually undetectable. They used salifert as well, they are going to try testing with a different manufacture.

Maybe they screwed up at the Kent factory and mislabeled the jug, gave you two calcium parts

What are you using for a salt? Are you adding anything to your system in the form of additives, dosing, etc?

I would think testing error. Even if you did not dose Mg and didn't do a water change in years your Mg should be higher than that.

I'm wondering if the tests are faulty? My Acro had RTN, i fragged it and now hoping it will survive. All my other sps and zoas seem to be healthy.
