ANS OPTI GLASS CO2 Diffuser Spiro 5000

ANS Opti Glass CO2 Diffuser Spiro 5000 for Planted Aquariums

The Spiro design adds a spiral glass path above the ceramic membrane, swirling the rising mist so bubbles spread sideways instead of shooting straight up in a single lane. We like recommending the 5000 to hobbyists running larger planted displays, because that gentle circulation spreads CO2-rich water more evenly across a planted layout and looks elegant doing it. The Opti glass keeps the whole piece discreet against your scape.

Place it low and toward the rear corner, letting the spiral disperse mist across the tank before it surfaces. In Singapore’s warm 27-29C water CO2 escapes quickly, so the extended swirl path helps more gas stay in solution through the photoperiod. The fine ceramic will slowly clog with biofilm and mineral residue from our tap water, so plan a periodic bleach soak to restore the bubble rate.

Confirm uptake with a drop checker rather than the bubble count alone. Read our CO2 diffuser guide and the aquarium CO2 guide, then explore CO2 systems.
