Penn Plax Bubble Discs / Air Stones
Penn Plax has always had some fine aquarium air stones. Their latest invention, the bubble disc, is becoming a favorite among aquarium owners as it offers a larger surface area for the bubbles, which is both more efficient and dramatic. They also still offer the Bubble Wall, which has always been a favorite for the backs of fish tanks. Add even more of an effect with a nice aquarium background or some dramatic aquarium lighting. Use the Add-a-Stone and combine several of them to add even more bubbles without having to run extra tubing around your tank. You may want to upgrade your air pump with all those new bubbles your tank will be able to showcase.
