Hmahli Hyper-Flow Series Sumps
Hmahli Hyper-Flow Series Sumps
Handcrafted in Wollongong, Australia, the Hmahli Hyper-Flow Series represents the pinnacle of acrylic filtration design. These systems are engineered for versatility, allowing aquarists to run three different filtration methods within a single sump layout: Triton Method, K1 Moving Bed, or a Conventional Sump layout.
Designed for both fresh and saltwater environments, the Hyper-Flow series combines robust construction with intelligent features like inbuilt ATO reservoirs and integrated dosing ports.
Customisation & Flexibility
Because every setup is unique, Hmahli understands that standard specs don't always fit custom plumbing.
- Need bigger connections? If you are using large pipework, we can adjust the bulkhead sizes.
- Specific placement? If you need connections in a certain spot to match your cabinet, just let us know.
Small changes are easy to make! Contact us prior to ordering to discuss your specific requirements.

FEATURES
GUARANTEED PERFORMANCE
BTA uses 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.
Transparent & Honest Performance Data
At BTA, we believe in intellectual honesty. Our specifications are clear, conservative, and designed to give you confidence in your purchase.
📌 UVT = 90% (Calculated for realistic water clarity)
📌 All dose rates are published at End of Lamp Life (EOLL) (Ensuring performance for the entire 16,000-hour lifespan)
📌 Pond volume calculations based on 1 turnover every 4 hours
📌 Aquarium volume based on 1 turnover per hour

DOSE RATES
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.
