  • Weighted to sink
  • Modular height
  • Easy to clean

Keep your aquarium well-oxygenated by using an air stone with your air pump. An air stone is used to diffuse the air into smaller bubbles that agitate the water surface and increase oxygen levels. We built our weighted air stones with little, modular discs that can be snapped together or removed to create the perfect size. Plus, its small diameter is perfect for fitting inside common air-driven devices, like sponge filters.

Nice bubbles for my 55g

replaced two Ziss air stones with these in my large aquarium Coop sponge filters, perfect size and stream of bubbles for my tank the weighted stones made them a breeze to install.

mixed feelings

Ok, air stone :) Definitely weighted and the green is great in a planted tank. I've played around with them using different air pumps and just not getting the amount of bubbles I prefer.
