Step-by-Step Aquarium Guide
Step 1: Choosing the Right Tank
- For beginners, 20–30 gallons is recommended.
- Larger tanks are easier to maintain than smaller ones.
- Decide on shape (rectangular is easiest to clean).
Step 2: Selecting the Location
- Avoid direct sunlight to reduce algae growth.
- Place on a stable surface that can handle weight.
- Keep near electrical outlets but away from high-traffic areas.
Step 3: Preparing Substrate and Decorations
- Rinse gravel or sand before adding.
- Layer 2–3 inches of substrate.
- Position hardscape (rocks, driftwood) before adding water.
Step 4: Filling with Water
- Use dechlorinated or conditioned tap water.
- For saltwater aquariums, mix marine salt to the correct salinity.
- Fill slowly to avoid disturbing substrate.
Step 5: Installing Equipment
- Set up filter, heater, and air pump.
- Adjust lighting for plants and fish species.
- Place thermometer inside the tank.
Step 6: Cycling the Aquarium
- The nitrogen cycle establishes beneficial bacteria.
- Run the aquarium for 4–6 weeks before adding fish.
- Test water regularly for ammonia, nitrites, and nitrates.
Step 7: Adding Plants and Fish
- Start with hardy plants like Java Fern, Anubias, and Amazon Sword.
- Introduce a few fish at a time to avoid overloading the filter.
- Gradually build your fish community.
