API Aquarium Test Kits, Water Care & Fish Food

Explore API aquarium test kits, water care products and fish food at The Tech Den Australia. Browse options for freshwater, saltwater and reef aquariums, alongside dedicated pond and turtle care products.

Water testing and aquarium care

  • Compare Freshwater, Saltwater, Reef and Pond Master Test Kits, individual parameter tests, test strips and replacement test tubes. Each kit measures a different combination of parameters, so check its contents before choosing.
  • Browse Tap Water Conditioner, Aqua Essential, Stress Coat, Quick Start and Stress Zyme, plus separate Ammo Lock, clarifiers, algae-control products and pH adjusters.
  • Find filter media including activated carbon, Ammo Chips, Ammo-Carb, Nitra-Zorb, Phos-Zorb, Bio Chem-Zorb and Water Softener Pillow.
  • Explore fish-care treatments including Melafix, Pimafix and Bettafix. Follow the individual product label for intended use, dosing and restrictions.

Fish food and planted aquarium supplies

Compare tropical and goldfish flakes and pellets, betta and cichlid foods, bottom-feeder pellets, algae-eater wafers and holiday feeding blocks. Choose food type and pellet size for the fish you keep. Plant products include Leaf Zone, Root Tablets and CO2 Booster; these are separate products with different applications, not interchangeable fertilisers or CO2 equipment.

Pond and turtle products

The range also includes Pond Care testing, conditioners, clarifiers, algae-control products and aquatic plant food tablets, plus Turtle Water Conditioner, Sludge Destroyer and Turtle Fix. Match the specific formulation to your setup rather than assuming aquarium, marine, pond and turtle products are interchangeable.

Check pack size, concentration, instructions and compatibility with your livestock, plants and filtration before use. Water conditioners, bacterial products, filter media and treatments serve different purposes. Check individual delivery details, especially the special-order 22.6kg aquarium salt listing, which carries additional bulky-item delivery costs.
