Hey all, I wasn't sure where to post this question, so if it needs to be moved feel free to move it to the correct location. Anyways I am working on setting up a 5.5 gallon betta tank and need some help setting the air pump up. I have the air pump, tubing, check valve, air control, and sponge filter. I have never used a pump before and I trying to figure out how to set the pump up correctly. Right now I have the air pump sitting behind the tank, and am trying to figure out the order that the air control and check valve go on and where they should be placed in the tubing. Thank you all in advance for the help.
