What Kind of Air Stone Should I Use?

  • A bigger air stone needs a more powerful pump to produce more bubbles.
  • Basically, bigger stones can produce more bubbles and they’re used for powerful air pumps.
  • If you connect a big air stone to a small pump, the bubbles will be produced only at the front of the stone.
  • Small pumps go well with smaller stones while powerful pumps and small stones don’t get along well.
  • A disc-shaped air stone can stay steady at the bottom of your tank, while cylinder stones will move around the tank freely.

    These are excellent for 5-Gallon DWC buckets. Perfect for many sizes of air pumps and makes a lot of bubbles. Get several of them because you will appreciate these.

  2. Danio

    Creates even amount of bubbles throughout; Low air pressures will produce very fine bubbles, while high pressures will generate lots of 1/4″ and finer bubbles. High pressures (20-40 gallon air pump) will create lots of surface disturbance and some localized current flow in a 20-gallon long. Seems to work more effectively face-down so there is more surface area for the bubbles to escape vertically. Recommend!

  3. LBBP

    Good-sized stones that produce as many (if not more) bubble action than some of the larger ones. Not terribly heavy, but still a good weight for my hydroponics set up. Good buy.
