Things You'll Need
- Scissors
- Micro airflow valve
Instructions
Cut the plastic air tube that connects the air pump and the tank's accessories with a pair of scissors so the micro airflow valve can be installed. If you are only restricting the airflow on one tube it doesn't matter where you cut it. If you are installing an airflow valve that has multiple air flow ports to allow you to control the flow rate to several accessories, it's important that each tube going from the valve to the accessories is the same length. This will allow for even distribution of air flow.
Install the micro airflow valve to the tube extending from the pump and to the tube that is going to the accessory. If you are using a valve with multiple ports, all accessories should be hooked up. Micro airflow valves are often equipped with check valves that allow air to flow in only one direction. This prevents water from siphoning through the tube in the event of a power failure. The direction of the flow should be oriented so the pump can power the tank's accessories.
Adjust the flow of air going to the tank's accessories using the open/close handle located on the micro airflow valve until you have reached the desired flow rate.
