Saltwater Aquariums: Water Chemistry Essentials

Maintaining optimal water chemistry is crucial for saltwater aquariums. Key parameters include:​

  • Salinity: Ideal specific gravity ranges from 1.020 to 1.025.

  • pH Level: Should be maintained between 7.8 and 8.5.

  • Ammonia and Nitrite: Both should be at 0 ppm to prevent toxicity.

  • Nitrate: Keep below 20 ppm to avoid algae overgrowth.

  • Calcium and Alkalinity: Essential for coral growth; maintain calcium between 400–450 mg/L and alkalinity between 8–12 dKH.

  • Magnesium: Crucial for overall water chemistry; ideal levels are 1250–1350 mg/L.​

Regular testing and adjustments using appropriate additives ensure a stable and healthy marine environment.

  • Water Changes: Regularly changing 10–20% of the water every 1–2 weeks helps remove toxins and replenish essential minerals.

  • Additives: Utilize water conditioners and trace minerals to enhance water quality and support the health of your aquatic inhabitants.​
