Compact and portable
Simple one-button designs and straightforward steps
Start testing right out of the box and control algae growth in aquariums
Regulating phosphate and nitrate is essential. Algae can grow rapidly and become problematic when these parameters are too high whereas levels that are too low will starve corals and disrupt biological processes. Enjoy hassle-free testing and incorporate our Marine Algae and Nutrient Management Kit as part of your reef tank maintenance routine.

Phosphate ULR Method
Adaptation of Standard Methods for the Examination of Water & Wastewater, 20th Edition, Ascorbic Acid Method.
The reaction between phosphate and the reagent causes a blue tint in the sample.
Nitrate HR Method
Zinc reduction method. The reaction between nitrate and the reagent causes a pink tint in the sample. This checker has been developed to work with seawater samples.
