What you are doing by running the co2 every now and again is causing unstable CO2 levels in your tank. This may lead to BBA. With that low of lighting IMHO your tank would do better in the long run by not having CO2, or have it going all the time.

BTW sorry for posting that photo. I though this thread was in the plant forum and not the photo forum.

True, the plants will put on growth when you add the CO2, but that growth then slows down again until you add it again. And unless you are using a bell-shaped diffuser which holds CO2, like in an upside-down bowl, the CO2 in the water decreases. Also, if it's a bell-shaped diffuser with CO2 under it, it's always a good idea to have some current under the diffuser, or the CO2 will go into the water at a much slower rate, thus, not doing much good. And as the other person posted, doing CO2 only now and then, you run a very high risk of BBA due to fluctuating CO2 levels.

Even though it is the same planet, underwater is a whole different world.

BBA? I'd be lying if I said I even knew what you were talking about. Maybe it wouldn't be so much to ask for people to actually use the full words as opposed to random shorter anacronyms.
