[APD] CO2 accident
Learn how not to set up a pressurized CO2 system from me. Last night I upgraded my CO2 from a DIY yeast sytem to a pressurized CO2 cylinder. I set the system up at approximately 15 bubbles/min using a low regulator setting and a needle valve. I woke up this morning to a fish massacre. Over night the bubble rate increased until there was a continuous flow of CO2. I'm not sure why this happened but I suspect it was because I did not allow the cylinder to warm to room temperature before setting the flow rate. When I picked up the cylinder from a welding supply store it had been stored outside at around 50 deg. F. I plan to reset the flow rate later after the CO2 level drops. Currently at 140 ppm and Ph was to low to measure. Be careful and keep an eye on a new set up.
