I see people panicking about this often so I thought I'd post. I am getting read to set up my NPT so I am really glad I happened upon it too.
BTW I was discussing the CO 2 injection with my Biology teacher (college) he isn't an aquariast but he often discusses the ecology of water systems. He was saying an oxygen meter would be a a good idea when injecting CO 2 because you can overdo or under do it (possibly killing your fish or invertebrates). I don't know where you get one yet but I will post if I find out.
