Marine Aquarium Salt, Reef Supplements & Water Care

Explore marine aquarium supplies at The Tech Den Australia, including salt mixes, reef supplements, coral nutrition, water tests and selected filtration media. Compare products from Red Sea, Quantum, Coral Essentials, Seachem, Aquaforest, Tropic Marin, Continuum Aquatics and Reef Anabolics for your saltwater setup.

Marine and reef aquarium salt

Browse salt mixes in a range of pack sizes, including bucket refills, boxed salt and buckets. Compare each formula's stated parameters and intended application, such as mixed reef, LPS or SPS systems. Follow the selected product's mixing instructions and check the prepared water before use rather than assuming every salt mix produces the same parameters.

Reef supplements and coral nutrition

Find calcium, alkalinity and magnesium supplements, trace elements, individual nutrient additives and multi-part reef care programs. The range also includes coral nutrition, amino-acid products and selected live phytoplankton listings.

Choose supplements according to measured aquarium requirements and the directions for your chosen program. Concentrations differ between liquid, powder and multi-part products, so they are not interchangeable dose for dose. Coral food and nutritional supplements serve a different purpose from products used to adjust water chemistry. Check storage instructions and product-specific feeding guidance.

Water testing and salinity measurement

Compare marine test kits and refractometers for monitoring your setup. Individual kits cover different parameters, including ammonia, pH, alkalinity, calcium, nitrate, phosphate or selected trace elements. Confirm what each kit measures before ordering, and follow the instrument's calibration and testing instructions.

Filtration, bacteria and nutrient management

Explore filter socks, activated carbon, zeolite, bacteria products and selected nitrate or phosphate management products. Nutrient-reduction products and nutrient supplements have opposite roles, so select them using test results and the needs of your aquarium. Bacteria and start-up products do not remove the need to monitor water quality while establishing a system.

Specialist marine treatments and coral dips

Selected listings address aiptasia, cyanobacteria, dinoflagellates and other specific aquarium concerns. Identify the issue before choosing a product and check its livestock exclusions, equipment requirements and application instructions. Do not assume every treatment is reef-safe. Coral dips have their own separate preparation and application directions and should not be treated as general display-tank additives.

Check pack sizes and purchasing conditions

Use individual listings for availability, dosing accessories and delivery restrictions. Selected heavy salt packs and bulk supplements carry additional delivery charges. Tropic Marin Pro Reef Salt 25kg and the Little Creatures live phytoplankton listings specify in-store pickup. Check the product page before ordering or visiting our Caboolture store.
