The Aqua Master Tools C800 Pro measures pH, EC and temperature in your reservoir and doses pH adjuster and nutrients automatically to keep them on target. It's for growers who want their feed held steady between visits, and who'd rather check a phone than a tank.
A reservoir doesn't stay where you set it. As plants drink, pH drifts and nutrient strength changes, often within a day. Correcting it by hand means the solution spends hours off target between checks. The C800 Pro checks constantly and corrects in small steps, so the roots see a steadier solution.
It doses in a measure, dose, wait cycle. You set how long each pump runs, from 1 to 900 seconds, then how long to wait before measuring again, up to 60 minutes. The wait gives the dose time to mix, so the controller doesn't overshoot. With C Series pumps delivering 1.5ml a second, a 10-second run adds 15ml.
The controller has two pump outputs. One runs a single pH pump, set to dose pH down or pH up. The other runs 1 to 5 nutrient pumps. You can use it as a full pH and EC controller, or for pH or EC alone.
The colour touchscreen shows live readings, alarms and history. The free Aqua Master Tools app adds push alerts, remote changes to set points and doses, saved dosing schedules you can reuse, and up to 12 months of graphs. If anything goes into alarm, dosing stops until you've checked it.
It corrects pH in one direction only, because it runs one pH pump. It also needs the reservoir to be circulating, with a pump or air stone. In a still tank, a dose sits next to the probe and gives a false reading.
Dosing pumps are sold separately, so you buy only the channels you need. If you only want to monitor, not dose, the W650 Pro Inline does that for pressurised lines.
Pumps connect with the cable supplied with each unit and clip together side by side.
The first C10 always goes on the pH output. The C20 and C30 are for nutrients only.
