Do You Need UV on a Reef Tank?
A UV sterilizer can reduce free-floating algae and some waterborne pathogens, helping with clarity and disease pressure. It is not a replacement for quarantine, good nutrition, or stable parameters.
How to Size UV Correctly
- Match wattage to system volume.
- Use a controllable pump so flow can be tuned.
- Slower flow generally increases sterilization contact time.
Placement and Plumbing Tips
- Install after mechanical filtration when possible.
- Use unions for easy bulb and quartz sleeve maintenance.
- Run continuously for consistency.
Maintenance Schedule
- Clean quartz sleeve every 1-2 months.
- Replace bulb on manufacturer schedule (often 6-12 months).
- Monitor temperature around the unit.
