Minimizes the visibility of CO2 equipment in the aquarium. Ensures maximum dissolution of CO2 in aquarium water. Allows for more consistent dosing of CO2. Compatible with 12 mm ID / 16 mm OD hoses. Overview:The Seachem 13 mm Glass Inline Diffuser is a pollen style inline CO2 diffuser that is placed in the outflow line of the filter or aquarium pump to efficiently diffuse CO2 gas into the aquarium. This placement of the diffuser avoids the need for a diffuser in the aquarium and significantly reduces the visibility of the CO2 injection system in the aquascape. This also allows for more rapid diffusion of CO2 into the system and can allow for more consistent levels and reduce waste of CO2 or overdose of CO2.Compatible with 12 mm ID / 16 mm OD hoses. Compatible with 6 mm (1/4") - Standard Airline Tubing. Suction cups included.Directions:Rinse glassware with warm water. Cut filter hose (Compatible with 12 mm ID / 16 mm OD filter hose) to appropriate length so that inline diffuser will hang vertically next to aquarium glass when filter outflow is placed on aquarium. Attach aquarium hose, ensuring that diffuser disc faces “up” toward outflow. Attach suction cups and desired tubing (Compatible with 6 mm (1/4") - Standard Airline Tubing) to the CO2 in line of the diffuser.Install check valve (not included) inline with 6 mm (1/4") tubing (CO2 in).To attach tubing and hose to glassware, wet the inside of the tubing or hose 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 or hose, do not pull tubing off of glassware. Instead, cut tubing or hose carefully along the attachment length to release the glassware.Mount your inline diffuser using the suction cup(s). It should be positioned so that it sits vertically on the side or back of the aquarium. When removing or repositioning the diffuser, pull by the suction cup(s) rather than the glass to avoid breakage.Once securely mounted, turn on filter. Ensure that water passes through diffuser and into aquarium without leaks or bubbles. Turn on CO2. Observe bubble count (bubble counter not included) and adjust CO2 to desired flow rate. Seachem Bubble Counter available for easy monitoring of CO2 flow.
