New with plants and not faring well.

I agree with andres. Keep it on but at a minimum. 6.8 should be about right and as long as the fish are ok you are good until you get a drop checker.

+1 for a bubble counter and a drop checker. The bubble counter on my regulator makes metering the CO2 very easy. I don't have a drop checker yet, so I've got the CO2 set at 1-2 bps. Building a drop checker is on my list for later this week.

Well none of my fish died last night; so that's a good thing.

But it seems that the co2 shut off after a few hours on it's own. Opening the needle a little more lets more co2 in again. I think my tank and its regulator/needle valve aren't keeping constant pressure. Drat.

How often do you guys refill your 5 lbs tanks? 1/mo?
