BigXor Posted November 17, 2015 Report Share Posted November 17, 2015 My display tank has injected CO2. It runs 6.2pH during the day and goes up to 7.0pH at night after I turn it off. Question is: if I want to have some PRL in the tank do I have to leave the CO2 turned on 24/7 ??? Quote Link to comment Share on other sites More sharing options...
