"lily pipe 出水喺放在水面上做成出水時有旋渦可以有除油作用" Who said that? You have to put the outlet pipe beneath the water. BTW, how do you set up your CO2 system? Do you have your CO2 dissolved inside the canister? Or, like most of us do, you simply put the outlet pipe near those CO2 bubbles and let them circulate evenly inside your tank? Anyway, if you just halfly immerse the outlet pipe, it will adversely impact the CO2 dissolving ratio which is not good for your plants.
Yea, you are right. The outflow just beneath the water not above. I mean if I use the CO2 disolver in between the canister (no matter inflow or outlfow in this case), does this effect the CO2 level?
I don't have the disolver on my tank yet and I'm using the disfuser inside the tank that what you just mentioned above.
Thanks.
