So I noticed after a few hours of my co2 being injected into the tank the drop checker wasn't as light green as normal. I checked my set up and I am now getting a problem with my reg I think stopping it from maintaining a constant working pressure. This makes for very irregular injection of co2. One minute it is going at about 1bps for around 20 seconds. It then has a sudden burst of almost 15-20 bps (approximate I can't count that quick) I have tried using the needle valve to adjust the rate but it feels broken or at least it's not working as well as when I bought it 5 months ago. With it being that old I will have to confirm the warranty etc but has anyone had this happen to them? The reg cost me £90 from a reputable aquarium website so not cheap(in my eyes anyway!) The regulator is an easyaqua dual gauge with built in solenoid. Any help greatly appreciated. I will try upload a video for reference of what's happening with the bps. I'm not massively concerned for fish ATM as the drop checker is still very green but I may turn co2 off anyway to be on the safe side.
