1. How UV Sterilization Works
UV-C light (254 nm wavelength) penetrates microbes (bacteria, viruses, parasites) and damages their DNA/RNA, preventing reproduction.
Does not alter water chemistry.
Requires pre-filtration (solids can block UV rays).
2. Key Benefits in RAS
✅ Effective Against Pathogens
Kills >99% of bacteria (e.g., Aeromonas, Vibrio), viruses, and parasites (e.g., Ichthyophthirius).
✅ Chemical-Free & Safe for Fish
No toxic residues.
✅ Improves Water Clarity
Reduces floating algae and fine organic particles.
✅ Low Maintenance
Only requires periodic bulb replacement (every 6–12 months).
