How to use an aquarium gang valve
A more efficient accessory for splitting one air stream into multiple paths is a gang valve. The model we offer features four outlets and up to two inlets. The two inlets allow you to add one or two air pumps as desired and then split it up four ways. Alternatively, you can connect daisy-chain two gang valves together, giving you eight ways to split your air.
Keep in mind that each time you split the air, each outlet has a weaker output and less air going through it. The more outlets you have, the more adjustments need to be made on each air stream. Luckily, there’s no need to get any air valves because each outlet has its own adjustable switch to regulate how much air goes to each individual device.
