Based on a famous ADA diffuser, this piece of glassware is specifically for aquariums up to 300L.

The large ceramic base allows for the high flow of CO2 to be passed though easily which is essential in larger aquariums. With smaller diffusers, if you increase the CO2 levels too much the bubbles become too large and shoot to
the surface without diffusing into your aquarium.

This diffuser can handle up to 4 bubbles per second.

Complete with 2 suction cups.

Tip: If you struggle attaching CO2 tubing to the diffuser, warm the tubing up first. It then slips on really easily avoiding any breakages.
