Can I Use Ozone in a Reef Tank Safely?
Quick Answer
Yes, but only through a skimmer with ORP monitoring. Start low and keep ORP around 300–350 mV to avoid stressing fish and corals.
Yes, ozone can be used safely in reef tanks when controlled properly.
- Inject ozone only into a protein skimmer or reactor designed for ozone use.
- Use an ORP controller and keep values conservative (roughly 300–350 mV).
- Run carbon on skimmer air/water output to remove residual ozone byproducts.
- Never dose blindly—watch fish behavior and test consistently.
If your goal is clearer water and better organics control, compare compatible gear in the ReefBay shop and log trends in the ReefBay app.
