AquaClear filters are a popular brand of aquarium filters manufactured by Hagen. They are known for their reliable performance and efficient filtration capabilities. AquaClear filters are commonly used in both freshwater and saltwater aquariums to maintain water quality and provide a healthy environment for fish and other aquatic inhabitants.

Here are some key features and information about AquaClear filters:

1. Filtration System: AquaClear filters utilize a three-stage filtration system, which includes mechanical, chemical, and biological filtration.
• Mechanical Filtration: The filter's foam insert traps debris, waste, and particles suspended in the water.
• Chemical Filtration: The activated carbon insert removes impurities, odors, and discoloration from the water.
• Biological Filtration: The BioMax filter insert provides a large surface area for beneficial bacteria to colonize, aiding in the breakdown of harmful ammonia and nitrite into less toxic nitrate.
2. Customizable Filter Media: AquaClear filters allow you to customize the filter media according to your specific needs. This flexibility enables you to select the appropriate filter inserts for your aquarium's requirements.
3. Hagen Cycle Guard System: AquaClear filters feature the Hagen Cycle Guard System, which helps maintain beneficial bacteria populations and ensures continuous biological filtration, even after cleaning or power interruptions.
4. Flow Control: AquaClear filters have an adjustable flow control feature that allows you to regulate the water flow rate. This feature comes in handy when you have delicate or slow-swimming fish that may be affected by strong water currents.
5. Easy Maintenance: AquaClear filters are designed for easy maintenance. The filter inserts can be rinsed or replaced without disrupting the beneficial bacteria colonies. Regular maintenance, such as cleaning the filter components, is essential for optimal performance.
6. Available Models: AquaClear filters come in different models, such as the AquaClear 20, AquaClear 30, AquaClear 50, AquaClear 70, and AquaClear 110. The model number indicates the filter's recommended aquarium size and flow rate capacity.

It's worth noting that specific product details, features, and availability may vary over time. Therefore, it's advisable to consult the latest information from the manufacturer or authorized retailers when considering AquaClear filters for your aquarium setup.
