Mastering Saltwater Mixing and Water Changes

Saltwater

Proper saltwater mixing is an art. Use RODI water only, mix salt to 1.025 SG at 78°F, aerate and heat for 24 hours before use. Perform 10-15% water changes weekly or 20-25% biweekly. Match temperature and salinity precisely before adding to the tank. Popular salt mixes compared: Red Sea Coral Pro (high alk), Fritz RPM (balanced), Tropic Marin Pro Reef (premium), and Instant Ocean (budget). Choose based on your coral needs.
