Magnesium Overdose Help!!!!!

[Terrence Cline]

Hi Randy

Trying to increase my magnesium levels and just tested using Red Sea test at 790. Added 95 ml of brightwell magnesion product to my 120 gallon tank + 20 gallon sump.

Help!!! Do I need to do massive water change to avoid killing my fish and coral? Please advise I need you expert help here.

Thanks in advance.

What does your tea kit say??

1500, 1600 are probably nothing to worry about. What number?

 

[Terrence Cline]

Red sea test kit showed 790 before I added 95 ml to increase it. Should I do water changers now or wait until tomorrow and retest?

Used brightwell magnesion product to increase magnesium

Luckily for you magnesion isn’t crazy potent. I regularly dose 22ml into my 59 gallon system and it only raises my mag 10ppm. Retest your mag and post your current numbers. With a result that low I get the feeling the test wasn’t 100% accurate

 

[purpfish]

that would only raise you’re mag like 20 ppm nothing to worry about at all

Great

Just completed 10% water change to be on the safe side. I will run another test in 24 hours to see how things look


Thanks

Try a different Magnesium Test and also check your salinity with a CALIBRATED device.

The Mag level you have posted is most likely an error

Do you have any snails? Are they moving or are they frozen in time? If they are moving, nothing to worry about.

I agree, very unlikely your magnesium is only 790.

This and your dose only added about 20 ppm mg

Why do companies have to include stupid instructions . Setting up a customer to fail if they try to follow this instruction.

"Always try to maintain the [Mg2+] within a range of +/-10 ppm"

Try the kit on some new salt water. I expect there is an error, which is so common the I do not recommend testing it:

Just say NO to magnesium testing: RMM is born

OK, this thread has been many years in the making, and I'm posting it here since folks in the chem forum are probably already tired of all the threads relating to problematic magnesium testing. I'm going to propose a method, let's call it the Randy Magnesium Method, or RMM for short. All good...
