Need advice running CO2
I just received my new CO2 regulator from GLA and this thing is sweeeet, But I need some advice running it. I have a 30 gallon tank with Finnex 24/7 plus running on sunrise to sunset mode. I have the CO2 setup at about 1.5 bubbles per second with the Selenoid on a timer from 6am to 7pm. I have a CO2 drop checker with 4KdH solution in it and I notice that its blue every morning and after a couple of hours of CO2 running it will become green the rest of the day (never yellow). I am trying to carpet some Dwarf Baby Tears. My question is, what times should I run my CO2 for the 24/7 cycle? All I can find is to start the CO2 a couple of hours before turning on the lights but my lights come on gradually.
I am also trying to carpet some S. Reapens in the tank as well. I have some anubias on wood and a sword that I grew since birth from a prior Sword I had purchased. I have a buch of neon tetras and a handfull of cherry red shrimp. Some small species of Plecos hanging around and a few mystery snails. And 1 lonely cherry barb.
Any advice is highly appreciated.
