It fits standard CO2 tubing and mounts vertically with the included suction cups. 5 Spiral Diffuser Features Five-turn spiral path extends CO2 bubble contact time inside the glass body. Fine ceramic atomizer helps produce uniform micro-bubbles. Clear glass construction keeps the diffuser discreet in planted aquascapes.

Mount it near gentle aquarium flow so the micro-bubbles can spread through the planted aquarium. Use care when handling the glass body and avoid forcing tubing onto the inlet. Using the Hygger 5 Spiral CO2 Diffuser Pre-soak the diffuser before first use, connect it to standard 4/6 mm CO2 tubing, and mount it vertically with the included suction cups. Adjust CO2 output slowly and watch bubble movement through the spiral. When bubble output becomes coarse or weak, clean the ceramic disc with a chlorine soak and rinse thoroughly before returning it to the aquarium.
