Quantifying Aquarium Water Quality: Determining the Essential Parameters to Measure (Explanation) in Fish-Exclusive and Coral-Inclusive Aquariums
In the world of reef aquariums, maintaining ideal water parameters is crucial for the health and vibrancy of corals and fish. Here's a guide to the key elements you should test regularly.
Calcium (Ca) is essential for coral skeletal growth. A daily check is advisable when adding corals to ensure optimal conditions.
Alkalinity (KH or dKH) is crucial for stable pH and coral calcification. A weekly regimen is probably best for testing alkalinity in a reef aquarium.
Magnesium (Mg) supports calcium and alkalinity balance. Testing should be done weekly to monitor demand.
Phosphates (PO4) can harm coral growth and promote nuisance algae. For a reef aquarium, phosphate levels should be kept below 0.05 ppm. Regular water changes and using phosphate-reducing filter media options or supplementation can help maintain ideal levels.
Salinity is important to maintain stable marine conditions. A refractometer calibrated at 20°C is recommended for accurate salinity readings.
pH reflects the acidity/basicity impacting coral and fish health. It should be monitored at all times for stability.
Additional parameters like ammonia, nitrite, nitrate, and hardness can also be relevant for overall tank health and fish welfare.
For accurate testing, digital colorimeter-style test kits are recommended. For example, the HIREEF2 Professional Reef Test Kit by Hanna Instruments measures calcium, alkalinity, phosphates, salinity, and temperature with digital readouts, allowing precise and user-friendly testing.
For even more comprehensive and precise analysis, sending water samples to specialized labs that use ICP-OES spectrometry technology, like Aquaforest LAB, can provide detailed profiles for a wide range of elements and guide tailored supplementation strategies.
Remember, the stability of aquarium water parameters is crucial for the health of fish and coral. A log of test results is helpful when maintaining ideal levels of these key parameters.

An aquarium test kit, such as the HIREEF2 Professional Reef Test Kit, is beneficial for monitoring key water parameters like calcium, alkalinity, phosphates, salinity, and pH, which contribute to the lifestyle and health of fish and corals in a home-and-garden reef aquarium. Regular testing and maintaining ideal levels of these parameters can lead to a more vibrant and stable aquarium environment.
