The pH in my tank varies from 7.6 (before lights and CO2 turn on) to 7.0 (after an hour or so of CO2). The RCS and fish seem happy and quite healthy - although it's been only a few days that they've had to endure the daily pH flux. Anyway, I was wondering how many of you run CO2 24/7 vs. how many run CO2 only with lights on.
