The DOOA CO2 Mini Diffuser (15) for slightly larger nanos

This is the 15mm filter version of the CO2 Mini Diffuser, giving a larger ceramic disc than the 10mm model. The bigger surface dissolves more CO2 per minute, so we steer Singapore hobbyists with the upper end of nano tanks, or a slightly higher bubble rate, toward this size. It still keeps the compact DOOA profile while comfortably feeding a denser small scape that pearls hard under good light.

Matching disc size to tank demand matters in our soft local water, which absorbs CO2 efficiently; the 15mm gives headroom for plant-heavy nanos without forcing the gas through a too-small disc. As always, watch your livestock and a drop checker rather than chasing bubbles alone. Clean the ceramic periodically, since our warm tanks coat diffuser discs with biofilm that slowly chokes the fine misting.
