Frequently Asked Questions
The questions we are asked most about the aquarium filtration and filter media for freshwater tanks we stock, plus the practical detail on orders, delivery and returns.
About our products
How do I know which filter size I need?
Every listing states the tank volume range the unit is rated for. If your tank is heavily stocked, size up one bracket rather than down.
Are replacement cartridges included?
The listing says so explicitly. Where a filter ships with a starter cartridge, the compatible refill packs are stocked under Filter Media & Cartridges.
Canister or hang-on-back?
Hang-on-back units are simpler to service and suit most tanks up to about 70 gallons. Canister filters hold far more media and run quieter, at the cost of a longer setup.
How long does delivery take?
Delivery times and carriers are set out in full on our shipping policy page.
Can I return a filter I have run?
Our return policy explains the window and the condition requirements. Please read it before running a unit you are unsure about.
