Can’t seem to get high Magnesium levels

[pinocchio]

No matter how often I change my water I can’t seem to get my magnesium levels up. I am using Instant Ocean (orange top) and it claims that at the right temp and salinity you can achieve Mg levels of 1350ppm. When I test my water I am usually around 1150.

My tank has a handful of zoas, a frammer, a dying frogspawn (which is what lead to the Mg investigation) and 1 crab. It also have a giant sand anemone and 1 bubble tip in case those change the chemistry some how.

Any thoughts?

maybe dose the correct amount of magnesium to the salt mix before doing a water change?

My mixing station isn’t heated. Won’t that affect results?

It takes a super large amount of mag to raise it at all… dosing a little bit here or there won’t really make a difference.. I’m sure @Randy Holmes-Farley has a calculator some where haha!

For the longest time I was use the purple top, so I am sure my levels were lower. But been using orange top for a couple months now. Was hoping to see better results.

Time for RMM:

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...
