Dual Environment Support: Specialized profiles for Saltwater and Freshwater aquariums, covering everything from pH and Ammonia to high-sensitivity Reef parameters like Phosphate and Magnesium. A Healthier Tank Starts with Better Data Accuracy is the difference between a thriving ecosystem and a crash.
