KH Controller Aquawiz Gen 4 measuring computer

Aquawiz KH Controller is an advanced aquarium computer that measures the KH level and - if it drops below the set target - automatically Dostering a solution of KH, maintaining stable conditions. It does not require additional reagents, generates e-mail notifications, connects to Wi-Fi, works after the power to be restored and communicates via BNC with pH / apex / Neptune systems.

A real breakthrough is the Δph indicator analysis function - an intelligent method of assessing the quality of water based on the difference between the current pH in the tank and theoretically maximum pH after a complete forward (pH (O)).

Δph = pH - pH (o) - This parameter allows you to assess the condition of the aquarium, regardless of the calibration drift or pH probe consumption.

✔️ The value above -0.3 means a stable and healthy environment in the tank.

✔ δph allows you to detect technical problems early (skimmer, aeration, co₂) before you notice them visually.

✔️ Allows you to experiment with tank parameters and observing effects in real time.

"Absolute values can be misleading - but differential values show the actual state."

The use of

• Automatic measurement and adjustment of KH level in reef aquariums.

• It maintains alkalicity in a constant range, responding to consumption by corals.

Functions

• Without reagents - uses reference water (aquarium or synthetic).

• KH dosage through a built-in peristaltic pump when the KH level falls below the target value.

• Measures the KH level automatically every 1-6h. The number of measurements over the day is editable.

• Wi-Fi and e-mail notification - sends alerts when the KH level requires intervention.

• BNC PH-KH OUTPUT - allows integration with Aquabiles / APEX / PH Controllers thanks to the conversion of measurements.

• No need for frequent pH calibration - detects the degradation of the electrode and signals its replacement.

Calibration and configuration

1. Initial installation

• Connect the reference water, pH-pride (BNC connector) and KH wires and power supply (12V).

• Set the device horizontally, close to the tank.

• Leave KH-Computer for 3 days to stabilize before connecting automatic dosing.

2. KH level calibration

• The device default assumes reference water; If necessary, synchronizes measurements with a manual test (eg a HANNA set). The user from "Kalamazeoreer" instructed synchronize the reference value with Hanna Measurement, which improved readings.

3. PH-PROFY CALIBRATION

• Automatic detection of electrode consumption; Manual calibration is not required, but you can calibrate if the indications deviate.

4. Wi-Fi and dosing configuration

• Enter through Wi-Fi to the interface on your phone. Enter the SSID, password, time zone, KH target set and measuring intervals.

• After configuration, you can remotely observe the charts, synchronize the data and catch the device in case of problems.

Equipment and specification

• Accuracy KH: ± 0.05 DKH; PH conversion: ± 0.01 pH.

• Peristaltic pump (3 / 5mm hose), reference tank ~ 0.6l.

• Power supply: 12V DC / 5A, Sizes: ~ 18 × 18 × 19cm
