My alk and calcium are always just shy of optimal with a pH of 8.3...I still manually dose to get to my target.
I experimented with different pH set points from 8.2 to 8.6 (before I had corals in the tank) and measured alkalinity over time. The pH of 8.3 gave the best balance of maintaining calcium and alkalinity close to target, but not over it.
I don't use a dosing device. I use a gravity feed of RODI water through a solenoid that has no issues being turned on and off at any duty cycle. The water flows into my kalk reactor and the overflow goes into my tank. Running for 6 months constantly with no issues.
