I purchased the JBL PH Controller as part of my CO2 setup (a decision that I am now beggining to regret) The 500g bottle the kit came with ran out within a week due to a faulty pressure reducer. Got that sorted and upgraded to a 2kg bottle which has lasted just 2 weeks. My bubblerate is around 1 per second. I imagine that the tank is been dosed with CO2 even when the lights are off, which is battering my CO2 supply. Would anyone advise putting the PH computer on a timer so it turns on/off with the lights. Would this work?
