air pump

[rems]

I have a 20 gallon tank with 2 clowns. What size air pump do I need and which do you recommend? I don't care about the price, I want the one that is the quietest and lasts the longest.
Also I want a bubble wall, what size do you recommend and which brand?
Do you guys prefer a bubble wall over any other airstone? Personally, I think it looks nicer. :D:question:

Most of us do not use airstones, we rely on protein skimmers, powerheads and sumps to get oxygen into the water

+1...air stones causes salt creep at the top of the aquarium from when the microbubbles pop. That's why they aren't used in saltwater tanks. But if you must have one, try to get one that's rated for twice the size of your tank.

Oh, I thought they were just an added plus for the tank.

No, they also can screw with the pH of the tank
