Set up a healthy home aquarium with this practical checklist.

• Choose tank size and location

  Pick a tank size that fits your space and fish plans; larger tanks are easier to keep stable.

• Verify stand placement on a level, stable surface
• Measure clearance and avoid direct sunlight or heat sources
• Assemble tank and check for leaks

  Fill partially and inspect seams before adding equipment or decor.

• Install and set up a filtration system rated for the tank volume

  Choose a filter appropriate for your tank and fish bioload.

• Prime filter and install media per manufacturer instructions

  Follow directions to avoid running an air-locked or dry filter.

• Add substrate and secure decorations

  Plan hardscape for hiding places and open swimming areas.

• Rinse gravel and decor thoroughly before placing

  Remove dust to prevent cloudy water and spikes in ammonia.

• Install heater and thermometer; set target temperature

  Set temp to species needs (tropical or coldwater) and monitor closely.

• Fill tank with dechlorinated water at the correct temperature

  Use a water conditioner to remove chlorine/chloramine before adding water.

• Start the nitrogen cycle (fishless or seeded media)

  Introduce an ammonia source or seeded filter media and be patient.

• Test water parameters (pH, ammonia, nitrite, nitrate) regularly

  Test daily during cycling and weekly after stable; keep ammonia/nitrite at 0.

• Create a fish stocking plan and add fish slowly

  Research species compatibility and add a few fish at a time to avoid spikes.

• Quarantine new fish for observation before introducing

  Use a separate tank for 1–2 weeks to check for illness.

• Establish a feeding schedule and portion control

  Feed small amounts 1–2 times daily and remove uneaten food after a few minutes.

• Set a weekly maintenance routine: 20–30% water change and tank check

  Consistent partial changes keep water quality stable.

• Rinse filter media in removed tank water; avoid full media replacement

  Preserve beneficial bacteria by using tank water to clean media.

• Keep emergency supplies: dechlorinator, test kit, spare media, nets

  Have basics on hand for sudden issues or water changes.

• Track logs of water tests, maintenance, and fish behavior

  Record results to spot trends and catch problems early.
