I am also a fan of CO2 Art regulators, I have them on 4 of 6 tanks and it will be 5 of 6 when DHL next delivers. I use Amazon Bluetooth timers. You may want to consider how you want your CO2 to enter the tank, I have gone to inline diffusers and I replace rather than clean the ceramic diffusers during scheduled maintenance. YMMV.
