TheUltramax 2000is part of AquaEl\'s series of technologically advanced canister filters. Based on patented solutions, the design ensures perfect water clarity, excellent ease of use and optimum water parameters in even the most demanding aquariums. This model is suitable for aquarium capacities between 250 and 450 litres, and has a flow rate of 1500 lph. ULTRAMAX– innovative, technologically advanced canister filters employing patented solutions. They are extraordinarily user-friendly and can be used in virtually any tank to purify water and maintain the required water parameters. They can be used in freshwater and marine aquariums. These are their main advantages: Unprecedented performance– the ULTRAMAX filters boast ahigh water flow rate (max. 1000 up to 2000 l/h) and can efficiently operate even in very large tanks (up to 700 l). In addition, being very capacious, they can hold large quantities of filter media. Filter media are placed in handy ergonomic baskets with acapacity of 1.9 leach (depending on the model, the number of baskets is 3 to 5). This guarantees extremely efficient mechanical and biological filtration. The filters are supplied with acomplete set of filter media carefully selected to meet the needs of atypical aquarium. Inbuilt pre-filter– the first of its kind in the market There is abig sponge pre-filter built into the lid of each ULTRAMAX filter (with acapacity of ca. 0.6 l). It is designed to capture course mechanical impurities before they can get inside the filter. In this way, the pre-filter protects the device from clogging, which reduces the required frequency of cleaning to aminimum. Instead, it is sufficient to regularly wash the pre-filter sponge in tap water. This only takes afew minutes and does not require disconnecting the filter from the power supply or taking it out of the aquarium stand. Exceptionally quiet operation: the excellent design of the pump rotor and the rotor chamber – grounded in more than thirty years of experience of AQUAEL’S engineering team – and the use of aceramic rotor shaft result in virtually noiseless operation. For this reason, the filter can be freely used in any room, even in abedroom. Exceptionally low power consumption– AQUAEL cares about the natural environment and helps its customers save money. That is why the innovative ULTRAMAX filters consume very little energy, which means lower electricity bills for aquarium keepers. The ULTRAMAX 2000 model only consumes 24 W per hour! Safety of operation– the water inlets and outlets in the ULTRAMAX filters are equipped with dual ball-valves that are extremely reliable. The valves prevent even the smallest water leaks and allow the hoses to be easily and quickly disconnected from the filter when it has to undergo cleaning and maintenance. The ULTRAMAX product line includes three filter models (ULTRAMAX 1000, 1500, and 2000) with the throughput capacity of 1000 up to 2000 l/h. Product advantages: the large volume of filter media creates ideal conditions for the growth of beneficial nitrifying bacteria inbuilt pre-filter ensures long operation without the need for cleaning free configuration of filter media fine performance control makes it easy to adjust the rate of operation to the user’s needs self-priming mode at the start-up exceptionally quiet operation thanks to the use of aceramic rotor shaft integrated cut-off valves
