I have a 46 gallon bowfront, planted, with very fancy guppies, cardinals and some misc fish. The pressurized CO2 started getting really flaky last week, and I replaced the tank. (It's a 5 lb tank that had been running since last December, it was due.) My aquarium maintenance guy set up the new tank for me and adjusted the solenoid valve. And warned me that I might have to fiddle with it for a day or two.
As far as I remember noticing, it worked fine last night. I walked in the room a few minutes ago and the CO2 was still going, even though the timer shut off at 9PM. Thinking my timer was flaky, I unplugged the solenoid totally, and it's still producing gas at the same rate. It's a Milwaukee valve, new last December, and has always been reliable.
I am assuming that the new tank just has a lot of pressure and needs to bleed down some before the valve can close. But that's a total guess and I do NOT want to kill any fish. (One of my hatchet fish disappeared yesterday, although I guess he could have jumped without us noticing...)
What should I do right now, tonite? The fish are acting normally, the drop checker (with 4dKH water) is a solid green, not yellow. The CO2 diffuser is bubbling away merrily. I do have a Koralia #1 powerhead in the tank and an airstone. The lights just shut off for the night. Should I panic?
