Testing magnesium

[Sophie"s mom]

Curiosity question here. How many here actually check their magnesium? How often? I have read a lot of differing opinions on this. Quite a few say no need to test if you are doing water changes, while others test it weekly and add as necessary. I have never tested mine, I don't even have a mag. test kit. But I am thinking about it. What test kits are most often used? I mostly have Hanna checkers, but I also have some Salifert. Just wondering which to get. For ease of use, and accuracy I really like Hanna, but Salifert I know is also quite dependable. Just curious what others here are doing.

I have little confidence in magnesium testing and recommend RMM for most folks:

Once a month icp for me , actually bumped it recently from 1250 to around 1350 if I got the dose right

I've had my tank for almost 3 years , I think I've tested 3 times .

I now do the RMM .

I checked it with ICP and it has been 6 months between tests.

Looks good to me…

RMM works remarkably well…
Best method for Mg management…

RMM for me also. Had a Hanna but i was better at guessing the level then the test was.

Thank you Randy, I was hoping you would comment on this.

I test once in a while, and it runs 1230's - 1280's. This is with a AquaForest test kit. Never read up on the RMM way.:thinking-face:

I follow @Randy Holmes-Farley's RMM. So, basically never.

RMM for me, iCP a couple times per year. No problems.

I don’t test calcium either, waiting for Randy to right up a nice article in support of my strategy :)

 

[JonoH]

RMM for me also :)

Have a Hanna tester that never gets used now!
