Magnesium Question
we have a biocube 29 hqi
and i added 1 level teaspoon of 'Reef Advantage Magnesium' my wife is freaking out saying i added way 2 much and i overdosed it and is acting like the whole tank is going to die.. tho i only used 1 teaspoon. like the instruction says. im not sure of our mag levels - but this is only the 2nd time we have added any magnesium to the tank in 4 months (thats how old the tank is) the salt we use in our tank is instant ocean reef crystals. can anyone tell me anything

Mag supplements are mostly water. It takes an insane amount to even budge the magnesium a little bit. You haven't done anything bad. You've barely made any change.

Not that anyone's getting ripped off, it's just that magnesium chloride and magnesium sulfate tend to absorb a ridiculous amount of water from the air. There's really little that can be done about it. So any time you get a mag supplement it's going to be mostly water.

As disc1 said...you are fine. However, if you are going to add anything to your tank, I would highly recommend testing. Just my cents...it is likely to help in the future.

+1 on testing before you dose. It's just good practice.
