Marine Aquarium Treatments & Reef Water Care

Shop marine aquarium treatments and reef water-care products at The Tech Den Australia. Explore Aiptasia control, cyanobacteria stain removers, coral dips, nutrient-removal media and reef supplements, alongside marine salts, bacteria products and test kits.

Aiptasia, algae and cyanobacteria products

Browse Red Sea Aiptasia-X, Blue Life Aiptasia Rx and Aquaforest Aiptasia Shot, plus Chemiclean, Fritz Slime Out and API Marine Algaefix. These products have different applications and instructions: identify the issue and check suitability for your livestock and aquarium before selecting a product.

Nutrient management and biological filtration

Find phosphate and nitrate removers, activated carbon and filtration resins from Quantum, Aquaforest and Blue Life. The collection also includes saltwater bacteria and aquarium-startup products from brands such as Fritz, API and Prodibio.

Base nutrient-management choices on water-test results and follow the product's dosing, media-use and equipment instructions. Continue monitoring ammonia, nitrite, nitrate and phosphate as relevant to your setup; bacteria products do not replace water testing or routine maintenance.

Reef supplements, salts and testing

Calcium, alkalinity and magnesium additives, including Quantum Aragonite, Red Sea Reef Foundation and Aquaforest formulations.
Trace elements, amino acids and vitamin supplements from Quantum, Coral Essentials, Aquaforest and Seachem.
Marine and reef salts from Quantum, Aquaforest and Tropic Marin.
Aqua One marine pH, calcium and phosphate test kits, plus dosing-bottle accessories.

Select supplements according to measured levels, aquarium volume and the manufacturer's dosing guidance. Different concentrations and formulations are not interchangeable.

Coral dips and fish treatments

Explore coral-dip products and fish treatments with product-specific applications. Check whether a product is intended for a separate dip, quarantine system or aquarium dosing. Inclusion in this collection does not mean a treatment is suitable for every reef tank, coral or invertebrate.

Read the full label for compatibility, aeration, filtration, skimmer and water-change requirements before use. Do not combine treatments unless the manufacturer specifically permits it.

Pack sizes and delivery

Compare pack sizes and treatment volumes on individual listings. Selected salt buckets, bulk media and larger supplement containers carry additional delivery charges for bulky or heavy items, calculated at checkout.
