Thank you for the quick reply - Just went out and picked up new test kits - will test again and get back.Make sure that your test kits are fresh and accurate. Then wait a few more days. My tank does not use calcium and alk in pure balance, but I can true it up about every 3-4 months with just a few tablespoons of dowflake (calcium chloride driveway melt).
Adjust your reactor based on carbonate and then adjust the calcium if you need to. I have never found it to work very well the other way
