Water Parameters and Maintenance

Water quality is paramount in a reef tank. Here are the key parameters to monitor and maintain:

• Salinity: Aim for a salinity of 1.023-1.025.
• Temperature: Keep the water temperature between 75-80掳F (24-27掳C).
• Ammonia, Nitrites, and Nitrates: Maintain low levels of ammonia and nitrites, with nitrates at 10-20 ppm.
• PH: Aim for a pH level between 8.1-8.4.

Regular water changes are essential for maintaining these parameters. A general guideline is to change 10-20% of the water every two weeks. Use reverse osmosis (RO) or deionized (DI) water for water changes to ensure the highest quality water.
