ADA Pollen Glass Large 20Ø for 60cm tanks

The Pollen Glass Large 20Ø is a side-mounted diffuser with its signature J-shape glass arm hooking neatly over the tank wall. We recommend the 20Ø for 60cm tanks growing light-hungry, CO2-thirsty plants such as Riccia, where steady, generous diffusion makes the difference between pearling carpets and stunted growth. The wide ceramic plate spreads fine mist across the front of the tank, and the elegant glass hardware suits the minimalist rimless setups popular among SG aquascapers.

The full glass construction, including that J-bend, is delicate, so we always tell customers to handle it slowly and never force it against the rim. Ceramic surfaces glaze over with biofilm and mineral scale, which our warm tanks accelerate, so a regular soak keeps the bubbles fine. Pair it with a check valve to protect your regulator and a drop checker so you can hit a stable, fish-safe level rather than guessing by bubble count alone.
