Reef Tank

[moryan86]

I wanted to ask here if anyone knew what is the easiest way to lower magnesium in my tank. I don’t have fish or corals and the tank is just about 1 year cycled. I tested with a salifert test kit and it’s telling my my Mg is over 2300 but not sure how it’s that high as I am using Instant Ocean Reef Crystal. Any suggestions would be helpful.

Try a different test kit.. no way it’s that high.. it’s a testing error.

I agree, try a different test kit that’s just crazy high

Or make sure you did the test correctly

You used a full syringe of reagent and then another half of a syringe?

What's your salinity, and how are you measuring it?

All Magnesium tests are very “finicky “, so to speak.
I struggled few times with Salifert and other test to get results, which would make sense. Any deviation from “standard procedures” may cause erroneous results and strangely in higher range. Unless you are dosing Magnesium?

What’s your calcium measuring? If it’s high “over 500” it will give you false mag readings with salifert..
