Hello to all. Just wondering what the heck.. So hoping someone can give me a bit clarity on this.. My previous CO2 bottle went for a pressured test and they said the head is leaking. Connected a new CO2 bottle last night. Did not mess around with the needle valve so CO2 is suppose to be the same out from bottle. Usually the fish could manage with the 6hours CO2 that gets pumped into tank but last night I almost lost all my fish.. Can it be because of the fishes that got adapted to no CO2 in the 2-3week period or was there really a big leak somewhere and now more CO2 gets pumped into tank? Thanx
Eish, you doing it wrong dude. When securing regulator to cylinder, your needle valve should be closed, your solenoid shut. You then fully open the cylinder valve to pressurize the regulator (if it's a working pressure adjustable reg, you'll continue to dial in required working pressure), switch on\open solenoid and slowly open\dial in bubble count via needle valve and closely monitor CO2 levels from there. When you haven't had C02 in tank for a while, always start out slow again and monitor your fish closely.
Needle drift\float is often an issue with cheap hobby grade kit, which again is why you cannot just assume the bubble count will be the same.
Ive got an Up-aqua regulator so far no problems. they told me the CO2 bottle needed a pressure test because it cant hold the refill and my valve on the bottle has a leak..
Likely just a leak at the cylinder valve, in which case they'd simply fit a new valve and do a simple pressure and leak test. If your cylinder is over 1o years old, they would have sent it in for hydro-testing.
Yeah they told me its over ten years old so it needs to go for the test. Ahw well luckily all the fishes survived and thnx for everyone's input
