5 Mistakes to Avoid When Setting Up Your First Aquarium
Setting up your first aquarium is exciting, but it's easy to make mistakes that can cost you time, money, and even fish health.
At PureAquatics, we help clients across the UK design, install, and maintain stunning aquariums, and we've seen it all. In this post, we'll walk you through the most common beginner mistakes to avoid so you can start your aquarium journey smoothly.
1. Skipping the Planning Stage
Don't buy equipment or livestock before planning your tank. Think about:
- Tank size and placement (away from direct sunlight and heating sources)
- Type of aquarium (freshwater, marine, reef)
- Your long-term goals: a small tank may seem easier, but larger tanks are often more stable for beginners.
2. Overstocking Too Early
It's tempting to fill your tank quickly, but adding too many fish too soon is one of the most common beginner mistakes.
- Your tank needs to cycle (build up beneficial bacteria) first.
- Overstocking creates excess waste, stressing fish and leading to poor water quality.
3. Choosing the Wrong Equipment
Filters, lights, or heaters vary significantly in quality and cheaper isn't always better.
- Choose equipment based on your specific tank size and type.
- Ensure your lighting is suitable for the type of plants or corals you plan to keep.
4. Neglecting Water Quality
Water changes and testing might sound boring, but they're crucial.
- Use dechlorinated water and test pH, ammonia, nitrite, and nitrate levels regularly.
- Perform partial water changes (10–25%) weekly or fortnightly.
5. Mixing Incompatible Fish
Not all fish get along. Some need different temperatures or pH levels; others are territorial or aggressive.
- Research compatibility before buying.
- Ask your aquarium specialist for stocking advice.
