Designed for Consistent Aquarium Water Parameters
Maintaining stable aquarium water chemistry is especially important in reef aquariums and heavily planted freshwater tanks.
Corals consume calcium and carbonate alkalinity as they grow, while planted aquariums may require regular replenishment of liquid nutrients.
Manually adding these supplements can become time-consuming, particularly when an aquarium requires multiple doses throughout the day.
The Hygger HG932 helps simplify this process by dispensing measured quantities of liquid at programmed times.
Instead of adding an entire daily supplement dose at once, users can divide the required amount into smaller portions.
This approach can help reduce sudden changes in water chemistry when dosing amounts are correctly calculated and monitored.
Important: An automatic dosing pump does not measure aquarium water parameters or determine the correct supplement quantity. Regular water testing and appropriate dosing calculations remain essential.
Four Independent Programmable Dosing Channels
The Hygger HG932 features four individually controlled peristaltic dosing pumps.
Each channel can be connected to a separate liquid supplement container and programmed according to the aquarium's requirements.
For example, a reef aquarium owner might configure the channels for:
Channel 1: Calcium supplement
Channel 2: Alkalinity or KH supplement
Channel 3: Magnesium supplement
Channel 4: Compatible trace element solution
For planted freshwater aquariums, the channels can be used for suitable liquid fertilizers and nutrient supplements.
Each channel operates independently, allowing different dosing times, quantities, and intervals.
This flexibility makes the HG932 useful for aquariums that require more than one type of liquid supplement.
Always confirm the compatibility of each liquid with the pump tubing and keep chemically incompatible additives in separate containers and delivery lines.
Up to 24 Automatic Dosing Events Per Day
The Hygger HG932 supports up to 24 programmed dosing events per day.
Users can set the time and quantity for individual dosing events, providing flexibility for aquariums that benefit from smaller, more frequent supplement additions.
For example, instead of adding a supplement in one large dose, the daily requirement can be divided into several scheduled portions.
This may be particularly helpful when maintaining calcium and alkalinity levels in reef aquariums.
The system also supports dosing intervals from 0 to 30 days.
Setting the interval to zero enables daily dosing, while other interval settings allow less frequent supplementation.
This makes the HG932 suitable for both everyday aquarium dosing and periodic supplement delivery.
Adjustable Dosing Volume and Flow Rate
The Hygger HG932 offers programmable liquid delivery with a specified dosing volume setting of 0–9,999ml.
The maximum pump flow rate is approximately 55ml per minute, allowing the unit to dispense suitable liquid supplements at controlled rates.
Because actual flow can vary with tubing condition, liquid properties, and installation height, the pump should be calibrated before use.
Hygger specifies dosing precision of approximately ±10%, making routine testing and calibration important.
For very small doses or highly concentrated supplements, users should confirm that the required accuracy is appropriate for their aquarium.
The HG932 is designed for automated liquid dispensing, not laboratory-grade precision measurement.
Individual Flow Calibration for Each Pump
The Hygger HG932 includes a calibration function for each dosing channel.
Calibration helps align the programmed dosing volume with the actual quantity of liquid delivered.
The manufacturer recommends using a graduated measuring cylinder with a capacity greater than 100ml.
Basic Calibration Process
Connect the inlet and outlet tubing to the selected dosing channel.
Place the inlet tube into the liquid container.
Use manual pump operation to fill the tubing and remove trapped air.
Position the outlet tube inside a graduated measuring cylinder.
Open the flow calibration menu on the controller.
Select the channel being calibrated.
Run the pump until the measuring cylinder reaches 100ml.
Stop the calibration cycle and save the measured value.
Repeat the process for the remaining channels.
Calibration Tip: Remove as many air bubbles as possible before calibration. Air trapped in the tubing can affect dosing consistency.
Recalibrate periodically, especially after replacing tubing, changing pump heads, or switching to a liquid with different flow characteristics.
Easy-to-Use LCD Controller
The Hygger HG932 features an integrated LCD display and control buttons for programming the dosing system.
The controller allows users to configure:
Local date and time
Individual pump channels
Manual pump operation
Flow calibration
Number of daily dosing events
Dosing intervals
Dosing volumes
Scheduled dosing times
The control panel includes directional buttons, an ENT confirmation button, and an ESC return button.
The straightforward interface allows users to configure the system directly without requiring a smartphone or Wi-Fi connection.
Once the dosing schedule has been programmed, the pump follows the selected settings automatically while connected to power.
Expandable from Four to Eight Channels
The Hygger HG932 includes four built-in dosing channels.
For aquariums requiring additional liquid supplements, the system supports connection to a compatible secondary four-channel pump unit.
This allows the controller to manage up to eight dosing channels when the appropriate expansion equipment is installed.
The expansion capability is useful for advanced reef aquariums and planted aquarium systems that require multiple independent liquid dosing schedules.
Note: The standard HG932 package includes four dosing channels. The additional four-channel expansion unit is not included and must be obtained separately if required.
Durable Peristaltic Pump Design
The Hygger HG932 uses a peristaltic pumping mechanism to move liquid through flexible tubing.
This design is well suited to measured liquid transfer because the supplement travels through the tubing rather than directly through the pump's mechanical drive components.
The pump heads are removable, allowing replacement when servicing is required.
Hygger identifies POM material in the pump head construction, selected for wear resistance.
The unit also features separate power and channel indicator lights, helping users identify when the device is operating.
Four non-slip feet help keep the pump stable on a suitable horizontal surface.
For best performance, install the dosing pump in a dry, stable location away from splashing water and excessive humidity.
Suitable Aquarium Applications
The Hygger Aquarium Dosing Pump HG932 is suitable for a range of aquarium maintenance applications, including:
Saltwater reef aquariums
Coral aquariums requiring calcium supplementation
Reef systems requiring alkalinity or KH dosing
Marine aquariums requiring magnesium supplementation
Trace element dosing in saltwater aquariums
Planted freshwater aquariums
