Sunleaves DIY Air Dividers allow you to oxygenate your reservoir exactly the way you want! 

These simple, but effective, Air Dividers attach to any length of 1/4-inch diameter tubing.

There are 4 to a package - shown connected together in photo.

Just separate the Air Dividers and connect together with tubing to create the layout best suited for your reservoir.

Each inline Air Divider can be individually turned on or off by twisting the valve at the top of the unit.

The last divider in the layout has a cap to seal it tight.
