I will be installing my pressurized CO2 system this coming week in my 50 gallon tank. What I'm thinking about doing is using the coralife digital timer to control my lights, c02, etc. I currently run my lights 5 hours in the morning and 5 hours in the evening. I can either use one or two 96 watt cf bulbs during this period. I like this as I can just manually turn on the 2nd tube for a couple hours in the morning and evening. I have a 4 inch air stone on the bottom in the middle and just use it occasionaly. What I would like to do is set the C02 to be on when lights are and the air stone at night. Would this be ok for the plants and I figure it would benefit the fish.
