Frequently Asked Questions

The Reef Master SPA is an automated water testing system. The F4 PRO Doser is a four-channel precision dosing pump. The E1 Module serves as a communication bridge, allowing the tester to control the doser (or a calcium reactor pump) for fully automated, closed-loop dosing.

No. Each unit works standalone. Many reefers use just the SPA or just the doser. You can expand your system later.

Yes. The SPA + E1 can control the Kamoer FX-STP pump for automatic calcium reactor adjustment based on KH readings.

The Kamoer FX-STP WiFi is a continuous-duty peristaltic pump designed for precise flow control-perfect for feeding calcium reactors. When paired with the E1 Module and Reef Master SPA, the system can automatically adjust calcium reactor output in response to real-time alkalinity levels.

Yes. The FX-STP WiFi pump will be available directly from kamoerusa.com. It integrates seamlessly with other Kamoer automation products.

KH: ~120 tests, Ca/Mg: ~150, NO2/NO3: ~50, PO4: ~90, Fe: ~300.

KH is often tested daily. Ca, Mg, and nutrients every 1-3 days depending on tank needs.

It's recommended to use the latest versions. Old/new reagents may differ in calibration and should not be mixed.

Yes, if the tubing and cap fit well. Always inspect for wear or residue buildup.

If test results differ too much from the last value, the SPA retests automatically. You can also set thresholds for test-to-test variation.

No. The E1 allows setting daily max doses, and dosing is only triggered if test values pass your safety checks.

Yes. You can disable dosing and just receive test data, using it for manual adjustments.

Bluetooth is used for initial setup. Wi-Fi allows remote access. Both are supported.

No. It works offline via Bluetooth. Internet is only needed for remote access and cloud backup.

No. The system is controlled via the Kamoer Remote app (iOS/Android).

Use the Reagent Cleaner (for KH, Ca, Mg) or NP Cleaner (for NO2, NO3, PO4, Fe) as dedicated reagent bottles. These run through the system just like any test reagent and clean the internal reaction chamber and pumps.

It's best to fully switch to new versions. Mixing old and new could affect accuracy.

Check for air bubbles, tight caps, correct tubing, and expired reagents. Retry the test and consult the manual if needed.
