Aquarium Advice Regular
I am currently setting up a 55g, just was wondering if the aquaclear 70 has enough gas exchange to make it where I dont need a air pump? I also want to point out that I don't like leaving the waterline lower then the rim of the tank. Idk if the filter is actually agitating the water surface enough. I have 2 AC 70's on a 55g.
