An update:
For awhile there my calcium was on the mend, now down to 380,
For awhile the alk was increasing >-- now down to 2.8.
Mag is around 1300 now.
Last Monday was a 20 gal water change. could be it?
All this with using the vinegar and 1.5 teas. of kalk, and I even believe I saw some additional coralline growth. I know I did as it was secondary layering over the first. I also was adding the b ionic at 30 mils each to see what happend. Am I adding to fast? This tank is driving me crazy.
I have mixed up some more kalk to run tonight, this time at 2 teaspoons of kalk, 30 mils of vinegar. I have also recieved some EVS magnesium and am bumping my mag up, 15 mils last sat and 15 mils today for a bump of 30 ppm total.
Am I right in this is the next step, up the kalk doseage to 2 teas?
I am about ready to buy a new bucket of IO, and get fresh RO and do a huge water change.
