Back to the drawing board...ALK and Cal

revhtree · Jun 16, 2017

I have been seeing these swings continue and I have been manually dosing each day to keep the alk up. Good thing is that is does go up, just not staying at 200ml per night. Have to manually does with that. Saw the Calcium start to drop as well.

My calcium was down by at least 30ppm.

Probably just testing error. Don't try to interpret small one time changes.

I didn't manually dose yesterday and my ALK dropped .8 DKH. I did auto dose 200ml during the night.

I was actually thinking about this yesterday for some reason. 200 ml is SO much! Sorry if I've missed it in one of your other threads, but have you started limewater yet? I'd be very interested in your results if you ever do. People say that you can get to a point that it can no longer keep up with your alk/ca needs, and I wonder if you're there yet.
