Need help from dosing experts

[Jaws]

Thanks guys. I have always used a calcium reactor in the past but I hate the constant tinkering around with the CO2 trying to always adjust to the growth rate of SPS. I've NEVER been able to keep up with the Alkalinity consumption in a reef with a calcium reactor either so I was always left with dumping alkalinity into the system which didn't keep levels constant the way I'd like them to be.

Any suggestions on what else you'd dose other than Ca, Alk, and Mg?
