Hight magnesium

[vtct]

Greetings to everyone, and congratulations to the parents: The magnesium in my aquarium is 1520. How dangerous is this, and how can I lower it? Thank you.

A water change would be best option to lower I’d say.

I don’t think 1500 is dangerous, but not certain. I will say that Vic from world wide corals gave his recommended parameters once, and his recommendation for Mg was between 1400-1500

Did you dose magnesium?

More likely than not, the magnesium test was faulty. We don’t test magnesium anymore for that reason.

Apparently it is tough to get accurate magnesium levels with home tests.

If you're doing regular water changes then there's almost certainly no issue.

If you did not dose a huge amount, it is likely fine and is exactly what the salt mix added. Thus, a water change won’t help.

I’d personally ignore the result, which is likely test error. I use and recommend RMM:
