ALK MINI

Manual colorimetric alkalinity checker

A clear colorimetric workflow for fast, repeatable dKH checks — with results you can log to the Nereus dashboard.

Devices

Two ways to keep alkalinity in view on the Nereus platform: a compact manual checker for quick spot tests, and a fully automated tester that runs on a schedule and writes results to your dashboard.

Alk Mini

Fast manual alkalinity checks

Alk Mini is Nereus’s handheld alkalinity checker — a dedicated colorimetric tester for quick, repeatable dKH spot tests. Run a reading, then log it to your Nereus dashboard so it sits next to controller and dosing trends.

Built for everyday reef testing

  • Colorimetric measurement focused on alkalinity (dKH)
  • Compact checker form factor for routine spot tests
  • Repeatable readings when paired with consistent reagent
  • Manual results that flow into Nereus platform charts
  • Designed to work alongside the reef controller and Dual-Head Doser

How to use

  1. Follow the Alk Mini test steps with a fresh sample.
  2. Use Nereus Alkalinity Reagent for consistent strength test-to-test.
  3. Enter the result in the Nereus platform (or your usual logging path) so alkalinity history stays next to live tank data.

Alk Mini is the simple path when you want lab-style alkalinity checks without a full automation rig.

Fully automated alkalinity tester

Alkchemist

Hands-off alkalinity on the Nereus platform

Alkchemist is Nereus’s fully automated alkalinity tester. It runs alkalinity tests on a schedule and pushes readings directly into the Nereus platform, so you see dKH trends without walking over with a checker every day.

Built for continuous reef chemistry

  • Automated alkalinity (dKH) testing on a schedule you control
  • Results written straight to the Nereus dashboard
  • Pair with controller data and dosing totals for a full chemistry picture
  • Less manual sampling once the unit is set up and calibrated
  • Same platform login as your reef controller and Dual-Head Doser

Who it’s for

Choose Alkchemist when alkalinity is something you want watched continuously — SPS systems, heavy dosing schedules, or any tank where missing a drift costs coral.
