I just bought one of these of craigslist for 15 bucks except the co2 bottle expired a month ago with a full tank of co2 in it, still a damn sick deal though.
Is it recommended to turn this thing off manually at night?
Jaggedfury leaves his on 24/7I leave it on 24/7. Needle valve is adjusted to 2bps. Been running like this for almost close to a year, no problems with tank or algae.
If I wanted to, I can always turn it off at night and turn it back on in the morning when my lights switches on. It's fairly easy to adjust, you'll be surprised.
