Two part dosing systems have separate solutions for Ca and Alk. You can adjust the amount you use to alter your levels. One popular two part dosing system is Bi-Ionic.
Thats what I mean by adjusting your dosing levels. Your Ca levels are slightly elevated, but not enough to get worried about, your Alk levels are high. If you are still using the all in one, I would either cut your amount in half, or not dose for a few days until your alk levels come down. You will need to test daily while doing this. Unfortunately, since you can't dose separately for Ca and alk with the system you are using, you run the risk of your Ca getting too low. The best recommendation I can give you is get away from the all in one and go to a two part system, get a mg test and find out what your levels are there, and use Kent Tech-M if needed to raise your Mg levels.
