What are the key features of the Hanna Complete Reef Testing Kit that benefit aquarists?
The Hanna Complete Reef Testing Kit is tailored for simplicity, accuracy, and reliability, making it easier to test and balance water quality. Its digital devices eliminate the guesswork of visual comparisons, delivering quick, clear readings. Each tool is pre‐calibrated or comes with the necessary solutions and reagents for accurate setup and maintenance. With this kit, aquarists can regularly track changes in key parameters and take proactive steps to maintain a stable, thriving reef environment.
What does each device in the Hanna Complete Reef Testing Kit do?
The Hanna Marine Alkalinity Pocket Checker measures carbonate hardness (dKH), essential for stabilising pH and coral skeleton development. The Hanna Marine Calcium Pocket Checker determines calcium levels, crucial for coral growth and structure. The Hanna Marine Phosphate Ultra Low Pocket Checker detects ultra‐low Phosphate levels, preventing harmful algae blooms. The Hanna Salinity Marine Pocket Checker gives fast and accurate salinity readings, using conductivity and providing measurements in ppt, PSU, or SG. Together, they cover all vital reef tank conditions.
