Reagent-Free Automatic KH Controller for Serious Reef Aquariums

Professional Alkalinity Monitoring. Intelligent KH Control. Zero Reagents. Zero Waste. Maximum Stability. Your Corals Don’t Care When You Test. They Care That Your KH Never Swings.

Every thriving reef aquarium has one thing in common: Stable Alkalinity (KH). Not expensive lighting.Not premium salt.Not designer corals.Not the latest wave pump.If alkalinity fluctuates, corals become stressed. Growth slows. Colour fades. SPS tips burn. In severe cases, prized colonies can be lost before the problem is even discovered.

The challenge is simple. Most hobbyists only test alkalinity once every few days.Your corals experience alkalinity every second. That’s where AquaWiz KH Controller Gen 5 changes everything.

Why Is KH So Important?

Alkalinity is the foundation of coral calcification. Every Acropora, Montipora, Euphyllia and other hard coral consumes KH continuously to build its skeleton. As your reef grows, alkalinity consumption increases. Without regular monitoring, KH slowly drifts. Most reef keepers don’t notice until they see:

• Burnt Acropora tips
• Reduced polyp extension
• Slower coral growth
• Faded colours
• Tissue recession
• Unexplained coral stress

The damage has already begun.

Traditional KH Testing Has One Major Limitation

Imagine driving from Delhi to Mumbai.Would you check your speed once……or continuously? Manual KH testing works the same way. It tells you where your alkalinity was when you tested.

It cannot tell you:

• What happened six hours later.
• Whether your dosing was enough.
• Whether coral growth increased consumption overnight.
• Whether KH dropped while you were at work.
• Whether your dosing pump failed yesterday.

AquaWiz fills these gaps through automated monitoring and control.

Meet AquaWiz KH Controller Gen 5

The next generation of intelligent reef automation. Unlike conventional KH testers, AquaWiz continuously measures alkalinity, tracks consumption, and can automatically adjust dosing to help maintain your target KH.

• NO reagent bottles.
• NO recurring chemical purchases.
• NO constant manual testing.

Just stable alkalinity. Every day.

Engineered for Precision. Designed for Long-Term Reliability.

The AquaWiz KH Controller Gen 5 is more than an automated KH tester—it’s a precision-engineered reef automation system designed to deliver consistent alkalinity monitoring and intelligent control with minimal maintenance.Every component has been refined to provide greater accuracy, improved reliability, and a better user experience for both hobbyists and professional reef keepers.

• Precision Reagent-Free KH Measurement

Unlike conventional automated alkalinity systems that rely on consumable reagents, AquaWiz uses an advanced reagent-free pH analysis method to determine alkalinity.

This innovative approach offers several advantages: No recurring reagent costs, No chemical waste, Reduced maintenance, Consistent long-term operation, Lower overall cost of ownership. The result is a cleaner, more sustainable approach to automated alkalinity monitoring without sacrificing precision.

• Laboratory-Level Accuracy

AquaWiz Gen 5 is designed to deliver highly repeatable measurements, helping reef keepers make confident dosing decisions.

Measurement Accuracy: ±0.05 dKH Error Margin: Less than 0.03 dKH

This level of precision enables the system to detect even small changes in alkalinity consumption, allowing timely adjustments before fluctuations become significant.

• Absolute pH Calibration — New in Generation 5

One of the biggest advancements in Gen 5 is the introduction of Absolute pH Calibration. This feature allows the system to be calibrated against trusted reference measurements, giving experienced reef keepers greater confidence that AquaWiz aligns with their preferred testing methodology.

The result is improved consistency, enhanced reliability, and greater control over long-term alkalinity management.

• Intelligent KH Control

Monitoring alkalinity is only half the solution. AquaWiz continuously analyses measurement data to determine your aquarium’s alkalinity consumption and automatically adjusts dosing to help maintain your chosen KH target.

Instead of reacting to instability after it occurs, AquaWiz helps prevent fluctuations before they impact coral health.

Three Advanced Dosing Modes

Generation 5 introduces multiple dosing strategies to suit different reef systems.

1. Smart Mode continuously adjusts dosing based on measured alkalinity trends and consumption.
2. Fixed Mode delivers a consistent programmed dose for mature, stable aquariums.
3. Bolus Mode provides scheduled correction doses for advanced users following specific dosing strategies.

This flexibility allows AquaWiz to adapt to a wide range of reef-keeping styles.

• Advanced pH Trend Analysis

In addition to alkalinity monitoring, AquaWiz continuously tracks pH behaviour throughout the testing cycle. Monitoring pH trends alongside alkalinity provides a more complete picture of aquarium stability and can help identify changes in biological activity, dosing performance, or system behaviour over time.

• Ultra-Quiet Operation

Aquarium equipment often runs continuously, making noise an important consideration for display tanks in homes and offices.

Generation 5 features redesigned internal components and an upgraded drive system engineered for quieter operation, reducing vibration and operational noise without compromising performance.

• Improved Mechanical Reliability

Every Generation 5 unit incorporates engineering refinements designed to improve long-term durability.These include:

• Upgraded motor assembly
• Reduced internal carbon dust generation
• Improved mechanical efficiency
• Enhanced component longevity
• Greater operational stability during continuous use

These improvements contribute to lower maintenance requirements and dependable long-term performance.

• Intelligent Connectivity

Built-in WiFi connectivity allows users to configure, monitor, and manage the system through a web-based interface using a smartphone, tablet, or computer.

Users can:

1. View live KH measurements
2. Monitor historical trends
3. Adjust testing schedules
4. Configure dosing parameters
5. Receive system status updates
6. Access health alerts remotely

• Controller Integration

For advanced reef automation setups, AquaWiz includes a BNC output that allows integration with compatible aquarium controllers such as Neptune Apex. This enables alkalinity data to become part of a broader automated reef management ecosystem.

• Compact Engineering

The sleek, space-efficient design fits neatly into modern aquarium cabinets while providing easy access for installation and maintenance. Every aspect of the enclosure has been designed with practicality, durability, and ease of use in mind, making AquaWiz suitable for both home aquariums and professional coral systems.

• Built for Continuous Operation

Unlike manual test kits that provide only occasional snapshots, AquaWiz is engineered to operate around the clock.

By combining precision measurement, intelligent control algorithms, robust engineering, and reagent-free operation, AquaWiz helps maintain one of the most important parameters in reef keeping—stable alkalinity—every hour of every day.

Why Reef Keepers Choose AquaWiz ? – 100% Reagent-Free Technology

Many automated KH systems rely on reagents that require regular replacement. That means: Ongoing costs, Waiting for consumables, Storage concerns, Chemical waste but AquaWiz uses a reagent-free measurement approach, eliminating routine reagent purchases and helping lower long-term operating costs.

More Than A KH Tester

AquaWiz is an automated reef management system. It:

1. Measures KH
2. Tracks daily consumption
3. Analyses trends
4. Calculates dosing requirements
5. Helps maintain stable alkalinity Instead of reacting to problems… AquaWiz helps prevent them.

Stability Is More Important Than A Number Many hobbyists ask, “What is the perfect KH?” well the better question is: “How stable is my KH?” Corals can adapt to a range of alkalinity values.

What stresses them most are sudden swings. AquaWiz is designed to minimise those fluctuations through continuous monitoring and intelligent control.

What’s New in Generation 5?

AquaWiz vs Traditional KH Testing

Why Reagent-Free Matters

When evaluating an automated KH system, consider the total cost of ownership, not just the purchase price. Reagent-based systems require ongoing consumables throughout the life of the aquarium. AquaWiz’s reagent-free design removes that recurring expense while reducing waste and maintenance.

For reef keepers running a system for years, this can make a meaningful difference in overall operating costs.
