NEW VERSION UPDATED

Aquael Ultramax 2000 Canister Filter | New Version 2026 | 2000 L/H External Aquarium Filter

Important correction: The product name you provided says “1500 L/H”, but the current Aquael Ultramax 2000 is officially rated at 2,000 L/H. I would not publish “1500 L/H” in the product title or specifications because that would be inaccurate. The current Ultramax 2000 is rated for 400–700 L aquariums, has a 16 L filter capacity, 5 × 1.9 L media baskets, and 21.5 W power consumption in Aquael's current specification.

Product Description

The Aquael Ultramax 2000 is a high-capacity external canister filter designed for demanding freshwater and marine aquariums. With a rated flow of 2,000 L/H, a large 16-litre filter capacity, and five 1.9-litre media baskets, it provides substantial filtration capacity for aquariums from approximately 400 to 700 litres.

The Ultramax 2000 features Aquael's integrated sponge prefilter, positioned inside the filter lid. The prefilter captures coarse mechanical debris before it reaches the main filtration chamber, helping reduce clogging and extend the cleaning interval of the main filter media. It can be accessed and cleaned conveniently without removing the complete filter from the aquarium cabinet.

The filter incorporates a self-priming system, double ball-valve system, adjustable water flow, and a ceramic impeller axis designed for quiet and reliable operation. The five large media baskets provide plenty of space to configure mechanical, biological, and chemical filtration according to the specific requirements of your aquarium.

The newer version incorporates Aquael's updated external-filter design, including updated inlet/outlet components introduced from 2025. This makes it important to distinguish the current version from older Ultramax 2000 specifications when purchasing or replacing accessories.

Filtration System

The Ultramax 2000 provides five 1.9-litre media baskets, giving a total basket capacity of 9.5 litres.

The integrated prefilter captures larger mechanical debris before it enters the main filter chamber. This helps protect the main filtration media from excessive debris accumulation and makes routine maintenance easier.

The media baskets can be arranged using appropriate:

• Mechanical filtration media
• Biological filtration media
• Chemical filtration media

This flexible configuration allows the filter to be adapted to planted aquariums, community tanks, large freshwater systems, and marine aquarium applications.

• High-capacity filtration for large aquariums
• 2,000 L/H rated flow for strong water circulation
• Large 16-litre filter capacity
• Five media baskets provide substantial media space
• Integrated prefilter helps capture coarse debris
• Easy-access prefilter simplifies routine maintenance
• Self-priming system makes startup easier
• Adjustable water flow allows output customization
• Suitable for freshwater and marine aquariums
• Low power consumption relative to its filtration capacity

How to Use

1. Position the Ultramax 2000 securely below the aquarium.
2. Arrange the required filtration media inside the five media baskets.
3. Connect the 19/25 mm inlet and outlet hoses securely.
4. Check all connections and valves before starting.
5. Fill and prime the filter using the self-priming system.

Important Note

• Clean the prefilter regularly to help maintain water flow.
• Disconnect the filter from the power supply before maintenance.
• Check hoses, valves, and connections regularly for leaks.
• Use filtration media appropriate for the aquarium's specific requirements.
