The HI782 Marine Nitrate High Range Colorimeter is specifically designed to quickly and accurately determine high levels of nitrate for saltwater aquariums and marine applications. With a digital read out, there is no more struggling to determine colors visually.
- Measurements with a range up to 75.0ppm
- Less complex laboratory grade accuracy – Requires only 1 reagent
- Simple, intuitive operation
- Compact and precise whether at home, at work, or on-the-go
Nitrate is the final step in the Nitrogen cycle. Excessive amounts of nitrates in saltwater aquariums facilitate the growth of undesirable organisms such as algae and dinoflagellates. The HI782 Nitrate Checker HC is a simple, accurate, and cost-effective way to measure nitrate from 0.0 up to 75.0 ppm (as NO3–) in your saltwater aquarium.
Using the Zinc Reduction method, a no filter process, The HI782 Nitrate Checker HC measures the concentration of nitrate colormetrically. Hanna Instruments Checker HC provides quick results in four easy steps
- For use with saltwater samples.
- More accurate than chemical test kits.
- Dedicated to a single parameter.
- Small size, big convenience.
- No errors with a digital readout.
- Ideal for aquariums and marine biology applications.
HI782 High Range Nitrate Checker vs HI781 Low Range Nitrate Checker
The HI782 was designed to quickly and easily measure nitrate levels for aquarist with higher-than-average nutrient levels. This includes saltwater aquariums that are fish-only or have corals that can tolerate elevated levels of nitrate at 30 ppm or more.
Very low levels of nitrate are critical for many saltwater reef aquariums, as nitrate can cause damage and possible death to certain delicate corals and invertebrates. For this reason, the HI781 offers unmatched precision in the measurement of very low levels of nitrate (0.00 to 5.00 ppm). For freshwater samples, Hanna Instruments recommends using the HI97728 Nitrate Portable Photometer.

LIGHT
LOW: Place coral at the bottom of the tank. Depending on the type, coral may need to be placed off sand and therefore mounted on a ceramic disc of piece of rock.
MEDIUM: Place coral at mid-range of the tank. Best placed/glued on top of a rock scape at mid-range height.
HIGH: Place coral from mid range to just below water level. SPS coral are shallow growing so they require and are able to tolerate intense light.
FLOW
LOW: Most soft coral do well with a small, gentle pulse. There are certain corals that can even be placed in areas of indirect flow, meaning places aside a rock structure or set into a entrance to a cave style space.
MEDIUM: Many LPS types of coral prefer medium pulse current. Most Euphyllia or corals that have more tissue structure connected to their skeleton, don’t like to be in a high flow area like the direct flow of the wave pump.
HIGH: Similar to high light, SPS enjoy being in some heavy current. Most LPS and SPS that branch encrust or plate prefer high flow that simulates the top water waves.
SKILL
ENTRY: While some may say beginner level, "Entry" is a good term to be used when starting out in the world of corals and marine life. Prior to adding livestock, you want to ensure that your reef has the proper parameters including zero levels of ammonia and nitrite. Seeing traces of nitrate in your waters is a good sign - just keep them at a lower level of 2ppm to 10ppm. Maintaining correct temperature and salinity are a huge factor to stable parameters. Starting to monitor your PH, alkalinity, calcium and magnesium is a great habit to get into to keep a successful reef.
While some soft coral don’t require too much light, having a proper reef light that puts out the proper pars is very important. You'll also want to have a good amount of flow and protected rock areas, as placing corals in their happy spot is ideal for success.
