Hanna Instruments Core Parameters Kit – Test Like a Pro Without a Lab Coat

 

Keeping coral happy isn’t just about good lighting and water flow. The Hanna Instruments Core Parameters Kit brings lab-level precision into your hands for monitoring alkalinity, calcium, and magnesium. With these compact digital checkers, you’ll swap frustration for four easy steps—and finally stop second-guessing your test kits.

HI772 Hanna Instruments Alkalinity Checker HC – Your pH Buffering Sidekick

Stable alkalinity keeps your reef from going off the rails. The HI772 makes it stupid-simple to check your dKH levels without messy color charts.

  • Measures alkalinity in degrees of calcium hardness (dKH)

  • Ideal for coral growth and pH stability

  • Takes less than two minutes to test

  • Built for reefers tired of guessing blue from blue-ish

How It Works:

  1. Zero the checker

  2. Add the reagent

  3. Insert the vial

  4. Read your result like a boss

Hanna Instruments HI758 Calcium Checker HC – Because Skeletons Matter

Tired of reading pinkish-lavender-purple test kits by candlelight? The HI758 gives you a digital readout so you know exactly where your calcium levels stand.

  • Measures calcium in ppm—no more color matching drama

  • Supports coral skeletal development and overall growth

  • Great alternative to finicky liquid test kits

  • Follows the same ZAIR method: Zero, Add, Insert, Read

Hanna Instruments HI783 Marine Magnesium Checker HC – The Unsung Hero

Magnesium might not get the spotlight, but it's the backstage pass for healthy reef chemistry. The HI783 is the only handheld magnesium checker that works with the Beer-Lambert principle—yeah, it’s science-y and awesome.

  • Accurately measures magnesium from 1000 to 1800 ppm

  • Ideal for both reef tanks and fish-only setups

  • Delivers consistent digital results with no test kit guessing games

  • Helps stabilize calcium and alkalinity levels by keeping magnesium in check

Why Hobbyists Actually Use This Kit (and Stick With It)

Let’s be honest: testing water sucks... unless it's quick, clear, and reliable. This kit is perfect for reefers who want dependable results without wasting an entire evening doing chemistry homework.

  • No more comparing shades of purple, pink, or confusion

  • All checkers use the same four-step process

  • Compact, digital, and surprisingly addictive
