Home Aquarium Setup

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.
