DIYL! - Hanna's Nitrate LR Checker

DIY Live!

Using @HannaInc step-by-step guide, we do a little live water testing using the new Nitrate LR Hanna Checker. It's super easy to use, and provides a guess-free nitrate value from 0-50 ppm

The HI781 Checker®HC (Handheld Colorimeter) is a simple, accurate, and cost-effective way to measure nitrate from 0.00 to 5.00 ppm (as NO3–) in your saltwater aquarium. For samples containing 5.0 to 50.0 ppm nitrate, follow the approved dilution procedure.

Nitrate is a by-product of the Nitrogen cycle. Excessive amounts of nitrates in a reef aquarium can promote the growth of undesirable organisms including algae and dinoflagellates while insufficient amounts can lead to starvation in which SPS and other corals will show signs including the loss of color and paleness.

The HI781 Nitrate Checker HC is a handheld colorimeter that uses the Beer-Lambert principle to determine the concentration of nitrate colorimetrically. The HI781 is designed specifically to measure low levels of nitrate in a saltwater aquarium.

I have yet to get a reading after 8 tests diluting not diluting watching every video I'm about done with this test

When you fill the syringe with the reagent is the little tube at the end hold 1ml worth of fluid? Which would mean you fill to 3ml not 4ml?
