Running two separate nutrient lines shouldn't mean adding two separate pump units to your setup. The Aqua Master Tools C20 packs two independent peristaltic pumps into a single compact unit, built specifically for accurate nutrient (EC) dosing — it's not intended for pH adjustment. Each pump delivers a standard dosing rate of 1.5 ml per second for fast, reliable delivery.
Its role depends on where you connect it: plug directly into the C800 Pro pH/EC Inline Controller right UTP port and the pumps appear as Pump 1 and Pump 2, or connect as an add-on to a C30 Peristaltic Pump Unit and they're automatically recognized as Pump 4 and Pump 5. Unlike the C30, the C20 has a UTP input only — no output — so it can't be expanded further with additional pump units downstream. A controller supports up to 5 EC pumps and 1 pH pump, for 6 pumps total per system.
An integrated side rail allows mechanical connection to other modules like the C30 or C10 single pump unit, and each pump includes its own manual priming button for filling or emptying food-grade dosing tubing individually during setup or maintenance.
Two peristaltic pumps in one unit, each dosing independently at 1.5 ml per second.
Connects directly to a controller or C30, automatically recognized based on placement.
An integrated side rail allows mechanical connection to other modules like the C30 or C10.
Each pump can be primed or emptied individually during installation or maintenance.

No, the C20 is only suitable for nutrient (EC) dosing and is not intended for pH adjustment. Use the C10 Peristaltic Pump Unit for pH dosing instead.
Connect the C20 directly to the C800 Pro controller's right UTP port, where its two pumps will appear as Pump 1 and Pump 2 in the controller menu.
Yes, connecting the C20 as an add-on to a C30 triple pump unit will have its pumps automatically recognized as Pump 4 and Pump 5.
No, unlike the C30, the C20 only has a UTP input and no output, so it cannot be expanded further with additional pump units downstream.
A single controller supports a maximum of 5 EC pumps and 1 pH pump, for 6 pumps total per system.
Each pump has its own priming button, letting you manually fill or empty its tubing individually during installation or routine maintenance.
