About aquarium equipment

Aquarium equipment keeps water clean, stable and suitable for fish and plants. The tank itself comes in glass or acrylic, with rimless and braced designs. Filtration includes hang-on-back filters, canister filters, sponge filters and sumps. Heaters keep tropical tanks stable, and LED lighting supports planted tanks and corals.

Planted tanks often add CO2 systems and specialized substrates. Marine and reef tanks need protein skimmers, powerheads and specialized lighting. Aquascapers use hardscape rock, driftwood and tools like tweezers and scissors.

Choose equipment rated for your tank's volume and setup. Plan for a sturdy stand, since full tanks are very heavy, and cycle a new tank before adding fish.

Choosing aquarium equipment

  • Match filter and heater ratings to your tank's volume.
  • Use a stand rated for the full weight of the filled tank.
  • Choose lighting suitable for fish only, planted tanks or reef.
  • For used tanks, check seals and test for leaks before setting up.
  • Plan for tank cycling before adding livestock.

Questions about aquarium equipment

What equipment does a beginner tank need?

A tank, filter, heater for tropical fish, lighting, substrate, water conditioner and a test kit.

Is it safe to buy a used aquarium?

Often, yes. Inspect seals and glass for scratches or chips, and leak-test it before setting up.

Canister or hang-on-back filter?

Hang-on-back filters are simple and affordable. Canister filters offer more capacity and hide under the tank.
