Specifications

What it is. A ceramic CO2 diffuser, M size, part of ISTA’s UFO CO2 Diffuser line (item I-523; S = I-504, L = I-505).

Design. Vertical CO2 input keeps the feed line running straight down rather than bent sideways, and the ultra-slim body is built to sit flush on the substrate — placing a diffuser at the bottom of the tank is what maximizes contact time between the CO2 bubbles and the water on their way up.

Maintenance. The ceramic disc is designed for easy removal and cleaning or replacement once it clogs, rather than needing the whole diffuser replaced. ISTA’s own wording: the silicate suction cup is chosen for reliable, firm attachment under continuous CO2 exposure.
