I'm running my Apex Classic on a planted tank with pressurized Co2. I'm controlling Co2 on/off based on the pH. But I'd like the on/off pH range to be different at night than in the day. For example, between 11pm and 11am I like the on/off range to be between 6.9 and 7.0. But for the next 12 hours I'd like the on/off range to be 6.7 to 6.8. Is this doable?
