I presume you are using CO2 tank? If you don't have a solenoid, then leave the CO2 running all the while to save you the trouble. I run mine non-stop at about 1 or 2 bps.----------------

Hi to all bros,
I am newbie to planted tank, just set up tank for almost 6 days now, just wondering should I on the co2 injection 24/7? What will it cause to the plant if on 24/7? As I do know that plant do not need co2 in the night, the only concern is the fishes right? Pls correct me if I am wrong. I have not added any livestocks yet.
Currently, I discover, in the morning, the PH is at 6 before lights on & in the evening the PH is at 6.5. Lighting currently is on for 8hrs a day, temperature is at 25 degrees.
Start to discover 1 of the plant, I think is call the Aponogeton ulvaceus, long stem - spiral leaves, start to develops brownish in color for those shorter ones, is this a sign of too much co2 or insufficient light?
Pls help.
Many thanks

With CO2 running all the time, of course the concern will be the fishes. SO ensure you have sufficient kH as buffer to prevent the pH from falling to very acidic levels.
For your A.ulvaceus, it's best to tell us more about the tank parameters/ fertilising regime as in this questionnaire. But my first suspicion is lack of major nutrients like N and P if you have not add any fertiliser containing nitrates.
