Calcium and Magnesium are too high!

[mochaclownlover]

Hello everyone!
So my Cal is at 500 ppm and Mag is at 1600 ppm. My Alk is at 7.0 dkh. I did a 50% WC with brightwell's neomarine salt mix two days ago and no change. I'm trying to get mag & cal lower, the WC didn't seem to change anything so what's the best way to lower these two elements? Any advise is greatly appreciated!

Did you test the new water?

I actually did not... I didn't even think of that. I was just looking at how much cal&mag were in the salt mix and tank test results from before and after. I will test some of the new water. Thank you

Finished testing the new water, mag-1500ppm , cal-470ppm , alk-7.0dkh
So it seems that at least mag is higher due to my ro water, but not sure how I would go about removing that from the ro water(just changed the ro filters about 3 months ago).
