Water changes should feel boring
The best reef water changes are consistent and predictable—not massive “reset” events. Corals dislike sudden swings in salinity, temperature, and alkalinity.
The stability-first method
- Mix saltwater fully (no rushed mixing)
- Match temperature
- Match salinity
- Change smaller amounts on a schedule
A simple schedule to start
- 10–15% weekly, or
- 20% every other week (if your tank is stable)
Don’t forget export
Water changes help, but flow/filtration do the daily work of keeping detritus from settling.
