Seachem Beetle Diffuser (27mm)

This CO2 diffuser with a 27 mm disk membrane is an ideal choice for dispensing CO2 into planted tanks between 20 and 50 gallons. 

Directions

Rinse glassware with warm water. Attach suction cup and silicone tubing to the diffuser. To attach tubing to glassware, wet the inside of the tubing with water at the attachment point and carefully slide tubing over glass. The use of other lubricants is not advisable as these usually make the tubing slide off of the glassware too easily. To avoid breakage when removing tubing, do not pull tubing off of glassware. Instead, cut tubing carefully along the attachment length to release the glassware. Mount your diffuser using the suction cup, it should be positioned low in the aquarium. When removing or repositioning the diffuser, pull by the suction cup rather than the glass to avoid breakage. Install check valve (not included) inline with tubing outside of the aquarium Once securely mounted, turn on CO2. Observe bubble count and adjust CO2 to desired flow rate using a bubble counter.
