Pressuried Co2 In A 2.5gal Tank

[Mikaila31]

Can anyone suggest a small CO2 diffuser for a 2.5gal tank.

Thanks,

Diffuser? AquaticMagic on eBay usually have some ting nano diffusers which are ~1cm in diameter for the ceramic disc. Other than that, AquaEssentials.co.uk may still have some Dymax Ceramic Atomisers left in their sale and these are superb for small tanks with pressurised CO2 - never used them with DIY but they may work OK.
