UVonic T5 UV Sterilizers MKII 5"
UVonic T5 UV Sterilizers MKII 5"
Why Smart Operators Choose UVonic
Three engineering principles that separate UVonic from every other UV sterilizer on the Australian market.
Rated at End-of-Lamp-Life (EOLL)
UV lamp output degrades over time. Most brands publish best-case new-lamp figures. Every UVonic flow rate is published at EOLL — protection that holds for the entire 16,000-hour lamp lifespan.
UVT 90% Design Standard
All UVonic units are sized to UVT 90% — the professional standard used in municipal water treatment and commercial aquaculture. Accurate sizing, conservative design, real-world results.
Verified by Bolton Photosciences
Every UVonic T5 design has been independently verified by Bolton Photosciences — the global authority on UV disinfection science. Third-party proof. Not marketing claims. Verified science.
Built for Professionals. Specified for Performance.
Every UVonic T5 MKII ships complete — no additional purchases, no missing adapters, no surprises.
Bolton Photosciences Verified
Independent third-party dose verification applied to every model in the range.
EOLL Rated Dose
Flow rates published at End-of-Lamp-Life. Performance guaranteed all 16,000 lamp hours.
16,000-Hour T5 Lamp Life
Premium T5 UV lamps — significantly longer than standard UV lamps, reducing running costs.
Heavy-Duty 5" PVC Body
Larger irradiation chamber delivers higher flow rates without sacrificing UV dose.
Imperial & Metric Unions
Both union types included. Installs into any existing plumbing — no adapters needed.
Integrated Sight Glass
Visual confirmation your lamp is running — simple, practical, absent on many competing units.
Countdown Timer & Indicator Light
Countdown timer tracks lamp hours. Indicator light confirms active UV output.
Professional Sizing Standards
Ponds: 1 turnover/4hr. Aquariums: 1 turnover/hr. Correct hydraulic sizing for real-world results.
Find the Right UVonic for Your System

Volume estimates calculated at 1 turnover/4hr (pond) and 1 turnover/hr (aquarium) at rated EOLL flow. For aquaculture and commercial system sizing, contact BTA for a site-specific assessment.
What's New in the UVonic Lineup
Continuous improvement — same engineering rigour, expanding capabilities.
UV28-T5 — 25W Upgraded to 28W
The UV28-T5 has been upgraded from 25W to 28W. If you previously had the 25W model, the replacement is now the 28W unit. Better UV output and flow performance — same price, same form factor, drop-in compatible.
UV40-T5 — New 40W Model
A new 40W model bridges the gap between the 28W and 48W units — ideal for medium ponds (~19,200 L) and larger display aquariums (~4,800 L). Flow: 80 lpm @ 30 mJ/cm² EOLL.
3" Diameter Models
A compact 3-inch body range is in development — same Bolton-verified engineering, EOLL dose rating, and UVT 90% standard. Designed for smaller systems, tighter installations, quarantine tanks, breeding facilities, and compact RAS setups. Register your interest → info@btaqua.com.au
Built for Serious Aquatic Systems
From premium koi ponds to commercial aquaculture — if pathogen control matters, UVonic delivers.
Ponds
Koi, goldfish, and native fish face continuous pathogen pressure. UVonic units sized for 1 complete pond volume turnover every 4 hours — consistent treatment on the correct hydraulic schedule.
Large-Scale Aquariums
Marine, reef, and high-stocking display systems demand aggressive UV programs. UVonic targets 1 full volume turnover per hour — meeting the elevated demands of closed recirculating systems.
Professional Aquaculture
UV240-T5 and UV310-T5 double-chamber models deliver industrial-grade UV capacity for RAS, hatcheries, nurseries, live seafood holding, and research facilities.
