ASF – Magnesium Test Kit

Overview

The ASF Magnesium Test Kit provides quick, reliable Mg readings to help you maintain stable parameters for SPS/LPS corals, clams, and other calcifying invertebrates. Consistent magnesium supports balanced alkalinity and calcium chemistry and prevents precipitation issues.

Key Features

• Reef-focused: Optimized for seawater magnesium testing

• Clear end-point: Easy-to-read color change for confident results

• Fast workflow: Simple steps; result in just a few minutes

• Repeatable: Calibrated droppers/syringe for consistent dosing

• Cost-effective: Multiple tests per kit (varies with usage)

How to Use (Summary)

1. Rinse the test vial with sample water, then fill to the marked line.

2. Add the indicated number of drops of Reagent A; cap and swirl.

3. Add Reagent B by drop (or via syringe, per instructions), swirling between additions until the color shifts to the end-point.

4. Use the provided chart/scale to read Mg (ppm) based on the number of drops (or syringe volume).

5. Rinse all components with fresh water after use.

Target guidance: Many mixed reefs run ~1,280–1,350 ppm Mg. Adjust for your system goals and follow manufacturer dosing directions when correcting.

Best Practices

• Test at the same time of day for consistency.

• Log results; re-test after large water changes or dosing adjustments.

• If results seem off, perform a control test with freshly mixed saltwater.

• Keep reagents tightly capped; avoid contamination of droppers and vial.
