Collection: Focustronic

How the Focustronic system fits together

Each Focustronic unit works on its own, but the range is designed to share data. A tester measures the water on a schedule, the result goes to the All in One app, and a doser can adjust its daily volume from that reading rather than from a hand test once or twice a week. The aim is small, frequent corrections instead of large swings.

Testers

• Alkatronic Professional tests alkalinity automatically and works to hold it steady, either on its own or paired with a Dosetronic.
• Mastertronic Essential tests calcium, magnesium, alkalinity, nitrate and phosphate in one unit, plus OLI, Focustronic's trend reading for how yellow the water is getting.

Dosers

• Dosetronic PRO has five independent channels on stepper motors, with continuous dosing and a two-pump automatic water change option.
• Dosetronic DC has five channels on smaller pumps, is built for dosing only, and works with the Alkatronic's dosing functions.
• Tracetronic holds up to 12 trace elements in 40 ml vials, premixes each dose with tank water and delivers it through a single hose on an hourly, daily or weekly schedule.

Reagents

Focustronic reagent kits are made for the Mastertronic Essential and come singly for calcium, magnesium, nitrate, phosphate and alkalinity, or as a full set. The Alkatronic takes its own Alkatronic CONC reagent. Focustronic does not list its kits for the original Mastertronic. The Mastertronic Essential also accepts off-the-shelf reagents, so testing can carry on if a Focustronic kit runs out between orders.
