Hanna Marine Magnesium Checker

What is the Hanna Marine Magnesium Checker?

The Hanna Marine Magnesium Checker provides an accurate way to measure magnesium within saltwater fish tanks. This checker is a digital reef water tester that provides clear information about the magnesium levels in your marine aquarium, enabling you to make effective changes to your water quality. Conducting regular aquarium magnesium tests is key to having the information to maintain a healthy tank. As with all checkers in the Hanna range, the Hanna Marine Magnesium Checker delivers accurate and fast testing results, with no guesswork required, and is operated by a single button, making it easy to use. The large LCD screen is easy to read and the auto shut-off feature ensures that the battery will not be drained.

How do I get an accurate measurement with my Hanna Marine Magnesium Checker?

There are many steps you can take to ensure the most accurate reading possible:

• Ensure that the sample does not contain any debris
• Hold dropper bottles completely vertically and squeeze slowly to ensure the correct drop size
• Whenever the cuvette is placed into the checker, it must be dry outside and free of fingerprints, oil and dirt
• Wipe the cuvette thoroughly with a microfiber cleaning cloth or a lint-free cloth prior to insertion
• Shaking the cuvette can generate bubbles, causing higher readings. To obtain accurate measurements, remove such bubbles by swirling or by gently tapping the cuvette
• Do not let the reacted sample stand too long after reagent has been added, as accuracy will be affected
• Discard the sample immediately after the reading has been taken or the glass might become permanently stained
• Prepare sample cuvette immediately after collecting the sample from the tank. Ammonia is volatile and will dissipate if stored in a bottle before analysis, causing low measurements
