If I wanted to expand my GHL Doser, what can I do with the Slave pump? Do I need to buy anything else such as additional cables?

The GHL dosing system can support up to 16 total dosing pumps. If you already have a dosing unit and wish to add a Slave doser, you can further automate your dosing tasks by dosing liquid foods and other supplements such as trace elements. When adding a slave dosing unit, you will also need to purchase a PAB-cable (available in various lengths).
