From Fresh to Salt
Transitioning from freshwater to marine reefkeeping is an exciting journey. While many principles remain the same, the ocean requires a slightly different approach to stability and chemistry.
The Main Differences
Salinity: You'll need to manage salt levels (Specific Gravity) using a refractometer.
Stability: Marine ecosystems are more sensitive to change. Slow and steady wins the race.
Flow: Corals need high, turbulent water movement (wavemakers) to survive, not just bubbles.
Chemistry: You'll monitor Alkalinity, Calcium, and Magnesium alongside Nitrates.
Basic Setup Needs
* You can often reuse your freshwater tank itself, provided it hasn't been treated with copper medications.
