  • Marine Phosphate Ultra Low Range Checker® HC – HI774


    The HI774 Checker® HC (Handheld Colorimeter) provides a simple, accurate and cost-effective way to measure phosphate in marine systems including coral reef tanks. Phosphate is an important parameter to measure in aquaculture and aquariums; levels that are too high can lead to extensive algae growth, depleted dissolved oxygen levels, and ultimately can be fatal to many types of fish and aquatic life. Designed as a more accurate alternative to chemical test kits, the HI774 provides quick, accurate results. For those that would like measure phosphate as phosphorous we off the HI736 Phosphorous Checker® HC. Alternatively, to determine the fraction of phosphorous (PO4-P) there is in phosphate (PO43-) the phosphate reading is multiplied by 0.3261. A 0.50 ppm phosphate reading is equal to 0.163 ppm or 163 ppb phosphorous.


    Phosphate Range 0.00 to 0.90 ppm
    Phosphate Resolution 0.01 ppm
    Phosphate Accuracy +/- 0.02 ppm +/- 5% of reading
    Phosphate Method adaptation of the Standard Methods for the Examination of Water and Wastewater, 20th edition, Ascorbic-Acid method. The reaction between phosphate and the reagent causes a blue tint in the sample.
    Photometer/Colorimeter Light Source LED @ 525 nm
    Photometer/Colorimeter Light Detector silicon photocell
    Battery Type/Life (1) 1.5V AAA
    Automatic Shut-Off after seven minutes of non-use and two minutes after taking a reading
    Environment 0 to 50°C (32 to 122°F); RH max 95% non-condensing
    Weight 64 g (2.25 oz.)
    Dimensions 86.0mm x 61mm x 37.5mm (3.4″ x 2.4″ x 1.5”)

  • Neptune Systems Apex Trident


    A key ingredient to a great reef aquarium is maintaining proper levels of Alkalinity, Calcium, and Magnesium.

    The Trident is an automated testing system that regularly tests alkalinity, calcium, and magnesium in your saltwater aquarium — and then communicates this information to your Apex so you can get alerts, and change your dosing. When combined with the DOS (available separately) it creates a fully automated system for the proper dosing of supplements, maintaining them at consistent levels.
