I've ordered everything I need off of Amazon and co2 art..waiting for it all to arrive this week. My main concern is "how" to start this slow....I've read to start injections hr prior to lights on and off 1 hr before lights go out. Should I just do an hr of injections every other day..and work up to every day then longer ect til I'm at all day long? Thats what I was gonna try anyway. I'll check out the other forums too

doing a bit of research and how should I do this with an existing planted setup w/ several breeds of fish and shrimp (1yr old) and NOT kill everyone? Start intro slow ? And how ?
