So in the last two months I've watched my calcium level fall like crazy. It's gone from 440 to now 280. My LFS
said to do a 50% water change this week then a 50% next week. Then go back to my normal 10% the following week. So I did the 50 last week and checked today and it's still at 280ppm.
I was told that the reason my calcium level dropped so much was that the magnesium level was depleted in my tank. I do dose with B-Ionic daily. But two months ago was using purple up. So once again my LFS
. Told me to increase the calcium dose by double, yet it has not helped. Any suggestions to what may be going on or how to raise my calcium. Thanks
