Aquarium Setup & Maintenance

Setting up and maintaining an aquarium can be a rewarding experience, bringing a beautiful slice of nature into your home. Whether you're a first-time fish keeper or looking to refresh your setup, this guide will walk you through the essentials of creating and caring for a healthy aquatic environment.

Choosing the Right Aquarium

Start by selecting an appropriately sized tank. As a general rule, larger aquariums are easier to maintain than smaller ones due to more stable water conditions. Think about where your tank will go—keep it away from direct sunlight and radiators to avoid temperature fluctuations and algae growth.

Equipment You’ll Need

To create a healthy environment, you'll need:

  • Filter – Keeps water clean by removing waste and toxins.
  • Heater – Necessary for tropical fish to maintain a stable temperature.
  • Lighting – Supports fish wellbeing and plant growth.
  • Gravel or substrate – For decoration and to support beneficial bacteria.
  • Water conditioner – Removes chlorine and chloramine from tap water.
  • Test kits – To monitor water parameters like pH, ammonia, nitrite, and nitrate.

Setting Up Your Aquarium

  1. Rinse the tank and equipment with plain water (no soap).
  2. Add substrate, rinsing beforehand to remove dust.
  3. Install equipment such as the filter, heater, and thermometer.
  4. Decorate with plants, rocks, or ornaments, ensuring all items are aquarium-safe.
  5. Fill with water, treating it with a water conditioner.
  6. Start the filter and heater, allowing the tank to run for at least 7 days before adding any fish. This period allows beneficial bacteria to develop—a process known as cycling.

Introducing Fish

Once your tank is cycled, start slowly. Add a few hardy fish first and gradually increase stock over several weeks. Sudden additions can overwhelm your biological filter and lead to poor water quality.

Always research compatibility and space requirements before choosing fish. Overcrowding is a common cause of stress and disease.

Ongoing Maintenance

To keep your aquarium healthy:

  • Test water weekly for ammonia, nitrite, nitrate, and pH.
  • Perform partial water changes (around 20–30%) every 1–2 weeks using a siphon.
  • Clean the glass and decorations as needed to remove algae.
  • Rinse filter media in old tank water—not tap water—to preserve beneficial bacteria.
  • Check equipment regularly to ensure everything is functioning properly.
  • Feeding & Fish Health

Feed your fish once or twice a day with only what they can consume in a few minutes. Overfeeding is one of the most common mistakes and can lead to water quality issues.

Observe your fish daily. Look for signs of stress, disease, or unusual behaviour, such as loss of appetite, clamped fins, or white spots.
