How the AquaWiz KH Controller Gen 5 Works

Unlike traditional alkalinity monitors that rely on chemical reagents or titration fluids, the AquaWiz Gen 5 uses a dedicated precision pH electrode to measure KH naturally. The controller compares your aquarium water against a stable seawater reference sample contained inside the unit.

By analyzing the pH response of both samples after controlled aeration, the AquaWiz calculates alkalinity with excellent accuracy without consuming any chemicals. This makes it an ideal solution for reef systems where stability, automation, and reduced maintenance are priorities.

Frequently Asked Questions

Does the AquaWiz KH Controller use reagents?

No. The AquaWiz Gen 5 is completely reagent-free and does not require test chemicals, cartridges, or refill fluids.

How does it measure alkalinity?

The system uses a precision pH electrode to compare the pH response of your aquarium water against a stable seawater reference sample, allowing it to calculate KH levels.

Does the reference solution need replacement?

The reference seawater is not consumed during testing and only requires occasional refreshing when needed.

How often can it test KH?

Testing frequency can be adjusted from every 1 hour to every 6 hours depending on your aquarium needs.

Can the AquaWiz automatically adjust alkalinity?

Yes. When connected to a compatible dosing pump, the controller can be used for automated KH correction.

What maintenance is required?

Maintenance is minimal. Periodic tubing inspection and occasional pH probe care are recommended. No reagents, cartridges, or consumable fluids need replacement.
