TestPro Pack Ca-KH-Mg — The Three Essential Reef Aquarium Tests - Aquaforest

Aquaforest TestPro Pack Ca-KH-Mg — essential test trio for reef aquariums

The TestPro Pack Ca-KH-Mg bundles Aquaforest's three fundamental tests — Calcium, Alkalinity (KH), and Magnesium — in a single economy pack. All three tests cover the macro parameters essential to tracking a reef tank whether SPS, LPS, or mixed-reef, with the precision of the individual kits and Aquaforest's ICP-OES + Marinlab certification.

Ideal starter pack for an aquarist setting up a weekly testing routine, or for renewing all three kits at end of shelf life at once.

What the pack contains

• Calcium Test Pro — about 55-65 measurements, reef range 300-500 ppm.
• Alkalinity Test Pro — about 78-100 measurements, range 6-14 dKH.
• Magnesium Test Pro — about 55-60 measurements, range 1,000-1,600 ppm.
• All necessary accessories (vials, syringes, charts and instructions).

Why test Ca, KH, and Mg together

• Ca/Mg ratio — a Mg deficit drops KH even if the KH dose is right.
• Calcium-alkalinity balance — abiotic precipitation if both climb too high simultaneously.
• Balling or Ca+/KH+/Mg+ tracking — full macro dosing management.
• Reef issue diagnosis — a macro imbalance explains 80 % of coloration or slow growth trouble.

Typical use on a reef tank

• Week 1 on a new tank — three tests a week to establish the baseline.
• Stable tank — weekly Ca + KH test, monthly Mg test.
• After a salt change — three immediate tests then weekly monitoring.
• Suspected instability — an immediate full test for macro diagnosis.

Frequently asked questions

Is the pack cheaper than three separate kits?

Yes — Aquaforest sells the pack at a combined price cheaper than buying the three individual kits separately. Recommended solution for a first test set or renewing all three at once.

Should I add PO4 and NO3 tests to the pack?

On an SPS or LPS reef tank, yes — nitrates and phosphates are critical to coral coloration and growth. The Ca-KH-Mg pack covers macros, but full NP tracking also needs Nitrate Test Pro and Phosphate Test Pro (sold separately).

How long does the pack cover a reef tank?

On a stable tank running weekly Ca + KH tests and monthly Mg tests, the pack covers about 6-9 months depending on exact frequency. Those durations match reagent shelf life — beyond that, precision may degrade and renewal is recommended.
