UVonic T5 UV Sterilizers MKII 5"

UVonic T5 UV Sterilizers MKII 5"

The New Standard in High-Flow UV Sterilization

Tired of underpowered UV sterilizers that can't keep up with your system's demands? Frustrated with inflexible units that are a nightmare to install and maintain?


Introducing the UVonic T5 (5" Series)—the ultimate UV sterilization solution, engineered exclusively for Biotech Aquatica. Designed for serious ponds, large-scale aquariums, and professional aquaculture systems, these units feature a larger 5-inch diameter body, delivering superior performance where standard sterilizers fall short.


We use the Bolton Photosciences Protocol for all our UV dosage calculations, ensuring our performance data is accurate, transparent, and based on real-world effectiveness.



🔥 Engineered for Performance and Practicality

✅ Enhanced 5" Body Design

The larger 5-inch diameter body is the core of our design. It increases UV contact time and allows for higher flow rates, delivering more effective sterilization with less pressure loss compared to standard units. More flow, more power, better results.


💡 High-Performance T5 UV Lamps

Equipped with premium T5 lamps from LightSources, guaranteeing a genuine 16,000-hour lamp life. Available in 25W, 48W, 87W, 120W, 155W, 240W, and 310W models.


🔧 Universal Sockets for Seamless Installation

Forget plumbing headaches. Every unit includes both imperial and metric union fittings, making it compatible with standard Australian PVC pipe and metric systems (like Sanking) right out of the box.


🛠️ Effortless Maintenance & IP65 Gland

Our NEW IP65 access gland and dual-end lamp access mean you can swap bulbs in minutes, not hours. You can also swap the inlet/outlet ends to suit your plumbing layout. No more wrestling with your gear.


🛡️ Zero Leaks, Guaranteed

The triple-seal quartz sleeve system (gasket, O-ring, and tapered cable seal) is engineered for a robust, leak-free seal and total peace of mind. This unit is built to be bulletproof.


🔍 Sight Glass for Easy Monitoring

The integrated sight glass gives you a clear, immediate visual confirmation that your sterilizer is operating correctly, taking the guesswork out of maintenance.


💪 Durable PVC Construction

Built to last with high-quality, heavy-duty PVC construction, ensuring extreme durability and a long service life even in the most demanding environments.

Understanding UV Dose Rates:

  • 30 mJ/cm² (Clarification): This is the industry-standard dose for controlling suspended algae (green water) and maintaining general water clarity in ponds and aquariums.
  • 105 mJ/cm² (Sterilization): This is a high-performance dose required for eliminating harmful pathogens, including bacteria and parasites like White Spot (Ichthyophthirius multifiliis). Choose this rating for quarantine systems or tanks with sensitive, high-value livestock.
