The Pawfly CW2020 accessory kit pairs 50 ft of standard 3/163 airline tubing (ID: 4 mm, OD: 6 mm) with a full set of parts for a multi-line air system. It is a good fit when one pump feeds several tanks, or when you want separate control over each stone and sponge filter.
In the kit
- 50 ft clear airline tubing
- 4 air stones, 0.83 D x 1.23 H
- 6 air control valves
- 8 connectors, straight and T
- 4 check valves
- 12 suction cups
Control valves make the difference

Most starter kits skip control valves. Here you get six, so each line can be tuned or shut off on its own. That matters when a sponge filter needs strong air and a nearby stone only needs a trickle, or when one tank in a rack needs less surface movement.
Air stones

Pawfly lists a jetting volume of 1.3 L/min for each small stone. They make dense, fine bubbles and are easy to drive with modest pumps.
Building a manifold

Use T connectors to split one pump outlet, then put a control valve on each branch. Fit a check valve between the pump and every line, arrow pointing toward the water. The suction cups keep tubing tidy along the glass so lines do not float.
Freshwater and saltwater
Pawfly says the kit suits both freshwater and saltwater tanks. The plastic tubing holds its shape and cuts cleanly to length.
Pump pairing
Splitting air needs a pump with spare output. The hygger quiet dual outlet pump or the larger AquaMiracle 600 GPH pump both work well with a kit like this.
Pawfly backs the kit with a 1 Year Manufacturer warranty, so a cracked valve or a split fitting is easy to sort out early on.
The Bottom Line
A well-rounded kit for anyone running air to more than one tank or device.
