The RenaCer Microbubblers are made of ceramic baked at 1800 degrees which produces smaller pores for smaller air bubbles.

The bubbles produced are a fine mist and can replace limewood type air diffusers in protein skimmers and other applications where very fine bubbles work best.

The ceramic material will last for years and will outlast any molded or wood diffuser. Calcium build-up may be removed by soaking in common household vinegar. The diffusers come in three sizes and can be attached end to end for bubble curtain effects.

Each unit comes complete with heavy-duty rubber suction cup and 3/16" tubing barb. These units perform best if used with higher quality air pumps such as the Rena Air series which operate at higher pressure than cheaper air pumps.
