The ADA Pollen Glass Mini is one of the most recognisable pieces of aquascaping equipment in the world, appearing in almost every Nature Aquarium layout presented by Takashi Amano and the ADA team. The hand-blown borosilicate glass body is crafted with the same attention to detail that ADA applies to all its glassware, and the Pollen Glass name derives from the pollen-grain appearance of the micro-bubbles produced by the precision ceramic membrane — bubbles so small they resemble suspended mist rather than visible discrete spheres.
The 20mm ceramic membrane used in the Pollen Glass Mini is manufactured to ADA's exacting tolerances and produces the finest bubble output of any standard in-tank diffuser available. CO2 dissolved at this bubble size achieves dissolution rates that measurably exceed those of larger-bubble competing diffusers at the same supply pressure. The all-glass construction means the diffuser body does not discolour or degrade over time, maintaining its aesthetic appeal indefinitely when properly maintained.
For competition aquascapers and dedicated Nature Aquarium hobbyists, the Pollen Glass Mini is both a functional tool and a design element — a piece of glassware that complements the refined aesthetic of a quality aquascape. It is sized for nano tanks up to 60 litres and pairs naturally with ADA's own CO2 system and pressurised CO2 equipment.
