Buying Guide
Choosing the right all-in-one saltwater aquarium depends on several factors. Consider these points before making a purchase:
- Size: Think about the space you have available and the type of livestock you want to keep. Smaller tanks (under 30 gallons) are great for nano reefs with smaller fish and corals. Larger tanks offer more stability and allow for a greater variety of inhabitants.
- Filtration: Check the filtration system. Ensure it has adequate mechanical, chemical, and biological filtration. Look for space to add additional media if needed.
- Lighting: Lighting is crucial for coral growth. Some AIO tanks come with basic LED lights that may be sufficient for soft corals. However, you may need to upgrade the lighting for more demanding corals like SPS.
- Flow: Water flow is essential for nutrient distribution and gas exchange. Make sure the included pump provides adequate flow for your tank size. Consider adding a wave maker for increased circulation.
- Budget: AIO tanks range in price from a few hundred dollars to several thousand. Determine your budget and find a tank that offers the best value for your money. Remember to factor in the cost of livestock, substrate, and other accessories.
- Experience Level: If you are a beginner, choose an AIO tank that is easy to set up and maintain. Look for models with simple filtration systems and straightforward instructions. Experienced reef keepers may prefer more advanced systems with customizable features.
