The Oase BioMaster Thermo 850 is an advanced aquarium filter that provides top-quality filtration and an adjustable heater for maintaining the optimum temperature level in your aquarium. The filter is designed to provide efficient and thorough mechanical, biological, and chemical filtration to ensure that the water in your aquarium remains clean and healthy for your fish and other aquatic inhabitants. The filter is suitable for both freshwater and saltwater aquariums up to 850 litres in size.

One of the key features of the Oase BioMaster Thermo 850 is its EasyClean pre-filter chamber, which makes filter cleaning extremely simple and convenient. The pre-filter chamber is easily accessible, and you can clean it without removing the entire filter from the aquarium. This saves you time and effort and ensures that your filter always performs at its best.

Another important feature of the Oase BioMaster Thermo 850 is the integrated HeatUp adjustable heater, which ensures that your aquarium water remains at the optimum temperature level for your fish and other aquatic inhabitants. The heater is adjustable and can be set to the desired temperature, providing you with complete control over the temperature in your aquarium. Additionally, the heater is integrated into the filter, which means that it does not take up any extra space in your aquarium and is not visible from the outside.

The Oase BioMaster Thermo 850 is designed to provide perfect water quality thanks to its high filter volume, which consists of Hel-X and filter sponges. The Hel-X media provides a large surface area for the growth of beneficial bacteria, which break down harmful toxins in the water. The filter sponges provide mechanical filtration, capturing debris and other particles in the water and ensuring that they are removed from the aquarium.

In terms of technical data, the Oase BioMaster Thermo 850 has a maximum flow rate of 1550 litres per hour and a maximum head height of 2.20 meters. The filter volume is 8 litres, and the pre-filter volume is 0.60 litres. The filter consumes 32 watts of power, while the heater consumes 400 watts of power. The filter comes with a 4-meter hose, and the connection for hoses has an inner and outer diameter of 16 and 22 millimeters, respectively. The filter weighs 7.05 kilograms and comes with a 3-year guarantee, which can be extended to 4 years upon request.

Overall, the Oase BioMaster Thermo 850 is an excellent choice for aquarium enthusiasts who want a reliable, efficient, and high-quality filter with an integrated adjustable heater. Its EasyClean pre-filter chamber, high filter volume, and Hel-X filter sponges make it a winning combination.
