Magnesium issue

[WarDog]

When I make saltwater for a w/c I test it for alk, Cal, and mg. If anything is out of whack, I just top it up using a reef calculator and chems from my dosing containers.

For example; IO is around 1100 ppm, so every time you do a water change you're going backwards unless you add Mg to the freshly mixed saltwater.

IO is only 1100ppm still? based on my test it's around 1200ppm, based on my expired Salifert anyway.

My tank sat at 1140 for years with IO, so somewhere in that range.

Sorry...typo! 1200 or a little less is what I've been seeing.

Interesting! I ran into something similar but in the opposite direction.....mag tested approx 2000.

Rolling the bucket didn't affect the readings for me.

Manufacturer did replace the bucket after I sent them a sample to test.

I'm in the why worry camp, although I don't have a lot of valuable sps either. I haven't been testing for anything for quite some time, something I did more regularly when I was new in the hobby & so was my tank. With the passing years, my best test is observing how the livestock & coral I have are doing on a daily basis. Haven't had a major crash, some critters including coral have died, but in my case, chasing numbers has never really solved anything in that regard. Every once in a while I will throw some baked baking soda, epsom salt or calcium into my top off container.

I understand testing for Potassium is the latest gig?

I don't test, but take potassium every day. And MG. And Zn.

I'm exactly same. I don't even have any test kits.

Rolling salt buckets has been talked/laughed about lots on here. Don't bother
