The Aqua Master Tools C Series pumps are the dosing units for the C800 Pro controller. They come in units of one, two or three pumps, so you can build a system with exactly the channels you need. The C10 handles pH adjuster or a single nutrient. The C20 and C30 are for nutrients only.
A peristaltic pump works by squeezing a tube with rollers, pushing a set volume forward with each turn. The liquid only ever touches the inside of the tube, never the motor or any metal. That's why it's the right design for strong pH adjusters, and why doses stay consistent from one week to the next.
Each pump moves 1.5ml a second, about 90ml a minute. That's small enough to correct a reservoir in gentle steps, and fast enough to dose a large tank without long run times. Thicker liquids, such as some silica products and boosters, move more slowly. Time a test run into a measuring jug and adjust your dose times to suit.
The motor is rated for 800 hours of running and the tube for 1,000 hours. At 1.5ml a second, that's around 4,300 litres pumped before the motor is due for replacement. When it is, you swap the pump cassette, not the whole unit.
The inner tube is Pharmed BPT, rated for phosphoric acid up to 85% and nitric acid up to 35%. Check the acid type and strength on your pH adjuster's label before you connect it.
These pumps need the C800 Pro controller to work as dosers. They don't run on their own, apart from the manual prime button.
The C20 has no expansion port, so it's always the last unit in a chain. If you think you'll add nutrients later, the C30 leaves room to grow.
