10 Best Aquarium Filters 2025 in the UK

The Fluval 207 External Filter is a robust option for aquarium enthusiasts, particularly those with fish tanks. One of its standout features is the Fluval eTEC construction, which employs an advanced design for efficient filtration. With a powerful motor, the filter delivers consistent pumping power and pressure, ensuring effective water circulation. Its flow rate of 780 liters per hour makes it suitable for medium-sized tanks, and it can handle up to 220 liters of liquid volume, enhancing its versatility.

Noise level is a critical consideration for many users, and the Fluval 207 addresses this by operating up to 25% quieter than previous models, thanks to its precision-crafted pump. This makes it a more pleasant choice for those who keep aquariums in living spaces or bedrooms. The filter also includes new ergonomic AquaStop valves that are designed for smoother operation, adding to user convenience.

The unique vertical pre-filter cartridge is a notable feature, offering more surface area for mechanical filtration, which is vital for maintaining clean water. Its independent access allows for easier maintenance, a plus for those seeking low-effort upkeep. However, there are areas where some users might find it less appealing. While it is designed for easy maintenance, first-time users may require some time to get accustomed to its setup and operation. Additionally, the item weight of 1.5 kg might be a bit heavy for smaller or more fragile setups.

In terms of compatibility, it is ideal for fish and covers all life stages, making it a flexible choice for various aquarium setups. Given its special features like ease of cleaning and durability, the Fluval 207 is a strong contender in the aquarium filters category, particularly for those prioritizing efficient and quiet operation.

The Fluval FX6 High Performance Canister Filter is an excellent choice for large aquariums, capable of handling tanks up to 1500 liters. Its standout feature is the impressive flow rate, processing up to 2130 liters per hour, ensuring efficient water circulation. The filter boasts advanced microchip technology that optimizes pump performance, making it smart and convenient. Its self-starting operation and automatic air removal every 12 hours add to its ease of use, eliminating common maintenance hassles. For those looking for a low-maintenance solution, the easy water change feature is a plus, as it does not require heavy lifting.

The filter includes removable and stackable media baskets that hold a significant amount of filtration media (1 gallon), preventing water bypass and enhancing the filtration process. However, the FX6’s size and weight, at 9.03 kg, mean it requires sufficient space and solid support. Potential buyers should consider the initial setup cost, which might be higher than other models. Maintenance appears straightforward but may require regular attention to optimize performance fully.

The Fluval FX6 is highly suitable for large aquarium owners seeking a powerful, intelligent, and relatively easy-to-manage filtration system, provided they have the space and are prepared for the initial investment.
