An air-driven sponge-filter reference for fry tanks, shrimp aquariums, quarantine systems and other setups where gentle flow and accessible biological media matter.
This is a preserved reference, not a live stock or price promise. Call (02) 4399 2358 to confirm the exact item, pack size and availability.
A sponge filter is simple but not maintenance-free. Size the pump and sponge for the tank, keep the lift tube clear and avoid replacing all mature media at once. In heavily stocked tanks it may need support from water changes or additional filtration.
We retained the established Leader Pet Supplies URL and checked the historical catalogue description against the named manufacturer or an authoritative Australian source where available. Product formulations, instructions, packaging and stock change, so the current label and manufacturer directions take priority.
Equipment and food choices cannot diagnose illness. Seek a veterinarian experienced with the relevant species for persistent appetite changes, pain, breathing difficulty, abnormal behaviour, weight loss or other health concerns. In an emergency, contact a veterinary service promptly.
