Actually, he was right, it was just air. I have a pressure valve, and i turned it down really low, so the oxygen was just seeping out slowly.
Anyways, I got the c02 going into the tank. I created a bell with a plastic bottle and window mesh per somebodies instructions. It seems to be working well however, should it be put in a place where there is good water flow? Ie. Beside the aquaclear intake?
I am a bit confused as to how this process works. So, if the C02 is trapped inside the bell it will eventually dissolve into the water?
Right now I don't see any bubbles on the plants, but when i put my hand in, there are tons of bubbles on it. Also, i turned off my UGF to minimize water disruption.
I have tried three methods, the aquaclear intake (it was kind of noisy and i heard that you lose a bunch of c02 when it comes out of the filter), chopstick -- it created really fine bubbles, it probably works, and this last method.
My ph seems to drop a little bit, but not to 7.0 or 7.2 like I want it to be. Right now i'm around a 7.5-7.8. I had my kh tested today and it was around 5.5 dh .
Any advice? I'm not using a cannistor filter, so an external reactor isn't an option.
