Can anyone tell what, besides low magnesium, would cause a lot of calcium precipitate? I have had my magnesium under control for a little over a week now but my calcium is drastically all over the place. I was dosing up to 540mL CaChl after I noticed the Mg problem. By this past weekend, I was maintaining a 450 Calc reading so I slowly brought the dosing down to 320. The last couple days I’ve had to bump the Ca dosing up 40mL each day because it’s hanging at 370-380. I can clearly see precipitation on my heater, skimmer and back glass. Am I missing something here or should I just keep increasing the Ca dosing until it levels off again??? I’m growing really frustrated....
