I am not new to planted tanks but I am new to co2 injection. I have a re-scaped 100 litre tank and I am blowing 1.5-2 bubbles per second. I have a 0.95L co2 tank (0.26 gallon aprox. (i think)). TARE weight is 1166g (2.57lbs). It is an aluminium tank. If this tank was filled full, how much would it weigh? On the tank the only marking that I understand is 0.95L, the tare weight I measured myself. The last time I filled my tank its total weight was 1500g aprox (3.31 pounds) altogether. Blowing 1.5-2 bubbles per second, the tank only lasted at most 5 days. I am very confused. I’ve asked some old aquascaping friends how long my tank should last and they said at least like 1-3 months. Definitely not so far. Am I being scammed by the people who fill my bottle? also please use metric or imperial measurements b/c i don’t understand the sciency crap lol...
