Choose products for your aquarium

Match each product to your aquarium type, livestock and intended use. Freshwater and marine treatments are not interchangeable, and a marine product should not automatically be assumed suitable for a reef aquarium. Check the current label for dosing, treatment duration, filtration instructions and livestock restrictions before use.

Oodonex listings advise against use with corals and invertebrates, Formalin Malachite is listed as a fish-only treatment, and Algicide listings warn against use with invertebrates such as shrimp. Other formulas also have specific precautions, so compare the individual instructions rather than relying on a blanket safety claim.

Water testing, conditioning and plant care

Use the appropriate test kit when monitoring or adjusting water chemistry. Mineral conditioning salts, blackwater additives and plant fertilisers serve different purposes. Compare your water parameters and the needs of your aquarium inhabitants before choosing a formula.

For planted tanks, compare Basic Gro, Daily Gro and Hydro Gro according to their liquid or root-feeding application and follow the product label. Check each listing for pack size, availability and any clearance notes. Selected 15kg packs are marked as heavy or bulky and incur additional delivery costs calculated at checkout.
