Marina Deluxe Bubble Disk

The Deluxe Bubble Disk lies flat on the substrate and pushes an even column of bubbles straight up, which is the simplest way to get a decorative bubble wall without lining up a row of separate stones.

Key features

• The flat disc shape can be buried at the edge of the gravel or hidden behind hardscape, so only the bubbles show.
• Output is spread across the whole disc, giving a steady display rather than a single stream that wanders off to one side.
• Offered in several diameters — choose from the size selector, or ask us which one suits your tank footprint.
• Connects to ordinary airline tubing from any aquarium air pump.

A wide disc asks for more air than a small stone, so a pump with an adjustable outlet, or a control valve on the line, makes it much easier to set the display where you want it. Like every diffuser it slowly clogs with mineral deposits and eventually needs replacing. Pumps, valves and tubing to go with it are in the rest of the Marina range.
