Handcrafted Sumps
The Foundation of Your Biofilter

BIOLOGICAL FILTRATION

High-surface-area media for maximum nitrification, ammonia removal, and gas exchange. The foundation of your biofilter.

K+ MBBR Media

Biofiltration

Advanced Moving Bed Biofilm Reactor media engineered for maximum nitrification. Bubble-washed design keeps biofilm active and prevents clogging in high-throughput reactors.

  • High surface area per cubic metre
  • Optimised for bubble-washed MBBR reactors
  • Compatible with bead filters
  • Long lifespan, low maintenance

TAN-X Chip

BTA Exclusive

Specialised ammonia removal media designed for direct TAN adsorption. Ideal for high-density hatcheries and quarantine systems where ammonia spikes must be eliminated quickly.

  • Direct total ammonia nitrogen removal
  • Works alongside traditional biofiltration
  • Emergency TAN crash protection
  • BTA exclusive formulation

HDPE Bioballs

Gas Exchange

High-density polyethylene bioballs providing dual gas exchange and biofilm support. Perfect for trickle towers, degassing chambers, and spray bar installations.

  • Excellent gas-to-water surface contact
  • CO₂ stripping and O₂ absorption
  • Durable HDPE construction
  • Suitable for trickle towers & sumps

Marine Pure Spheres

Deep Biofiltration

Ultra-high-porosity ceramic spheres (18.9L packs) designed for deep biofiltration and denitrification. Creates both aerobic and anaerobic zones within each sphere.

  • Extreme surface area per volume
  • Supports denitrifying bacteria
  • Ideal for reef sumps & high-flow reactors
  • Chemically inert marine-grade ceramic
Capture Solids Before They Break Down

MECHANICAL & CHEMICAL FILTRATION

Protect your biofilter and maintain water clarity with staged mechanical filtration.

SKM Protein Skimmers

Premium 20mm Filter Mats

Coarse Filtration

Heavy-duty filter mats for first-stage solids capture. Protects downstream bio-media from clogging and extends cleaning intervals in sump baffles and pre-filter chambers.

  • 20mm thickness for fine particle capture
  • Ideal for first-stage sump baffles
  • DIY drum filter pre-filtration
  • Reusable and easy to clean

Black Filter Foam

Pre-Filtration

Open-cell polyurethane foam for pre-filtration and surface filtration. Traps fine particulates while maintaining high water flow. Perfect for canister filters and pump cages.

  • Open-cell structure for high flow
  • Fine particulate trapping
  • Canister filters & pump cages
  • Custom-cut available

Aquael Canister Filters
