Aquarium buying guide
Common aquarium questions
How do I choose an aquarium?
Choose a tank size that suits your space and the adult size, activity level and compatibility needs of the fish you plan to keep. Allow room for appropriate filtration, lighting and routine maintenance.
What do I need for a new aquarium?
Most new setups need a suitable tank, filtration, water conditioner and a reliable way to test water. Heating, lighting, substrate and dΓ©cor should match the needs of the intended fish and plants.
How should I look after aquarium water?
Test water regularly, follow product directions for treatments and maintain a consistent cleaning routine. Make gradual changes rather than altering water conditions suddenly.
Are aquarium plants and ornaments suitable for every tank?
Choose decorations made for aquarium use, rinse them before setup and leave adequate swimming space. Check that shapes, materials and placement are appropriate for your fish species.
