The EHEIM aqua is a multi-functional internal filter with compact dimensions and a clever modular design. EHEIM aqua is a very easy to use internal filter for small to medium-sized aquariums. Ideal for beginners, it is simply attached to the corner of the tank with suction cups. Due to it’s compact size it takes up minimum space in the aquarium and leaves plenty of room for aquascaping. The powerful pump and large intake area ensure efficiency and the output can be easily adjusted to regulate both the water throughflow and the surface movement. In addition, a diffuser enriches the water with oxygen. The main feature, however, is the modular design: The filter containers can be easily removed for cleaning and, if you want to increase the filter capacity, you can extend it with additional canister modules.Advantages of EHEIM aqua Modular internal corner filter for small and medium-sized aquariums from 30 to 200 litres Ideal for beginners Compact and space-saving Practical suction cup attachment (4 suction cups) Powerful pump Simple adjustable output Large suction area to utilise the full filter volume Mediabox for different filter media (e.g. EHEIM AKTIV Kohle (carbon), SUBSTRATpro, phosphateout etc.) Clip-in filter containers (cartridges) for easy cleaning and expansion if necessary Includes diffuser and hose Supplied complete with filter cartridges for mechanical-biological filtration Including EHEIM AKTIV KOHLE (carbon - 20 g) for the Mediabox Suitable for fresh and marine water The modular internal corner filter with many advantagesThe EHEIM aqua corner internal filter was specially developed for small to medium-sized aquariums from 30 to 200 litres and offers many advantages. The filter is ideal for beginners and is suitable for both fresh and marine water.As a compact corner filter, it requires little space and therefore leaves more room for animals, plants and decorations.This multi-purpose filter promotes the mechanical and biological cleaning of the aquarium water in a single operation with permanent circulation, continual surface movement and a constant oxygen supply.The powerful pump and the large suction area contribute to the utilisation of the full filter volume and the diffuser enriches the water with oxygen. The water flow rate and the surface flow can be individually controlled using the simple regulator.The foam cartridges in the filter containers promote both mechanical cleaning and biological water purification at the same time whilst the activated carbon used in the Mediabox supports adsorptive cleaning. (In the Mediabox, filter sponges can also be used for chemical or additional biological cleaning instead of activated carbon).The modular design simplifies access to filter cartridges and cleaning. It is also possible to add further filter containers.

The new EHEIM aquaAlert+e is a high-precision, intelligent conductivity meter for continuously monitoring the water quality within your aquarium. By accurately recording the electrical conductance (μS/ cm), the device provides precise data on the salt content and potential contaminants TDS (total dissolved solids) such as sodium chloride, nitrite and nitrate ( build-up of organic waste). The device recognises such changes at an early stage, it will reliably warn you if limit values are exceeded and will provide specific recommendations for necessary measures such as water changes or water hardening to ensure a stable water quality. Thanks to smart algorithms, EHEIM aquaAlert+e also calculates the estimated time until your next water change and therefore supports optimum maintenance of your aquarium.The integrated temperature measurement also aids with safety: if the water temperature rises above a predefined value, the appliance will sound an alarm. The dry-running warning and electrode cleaning reminders also help you to keep the water quality at the highest level in the long term or can warn you if there is a need to top up the aquarium or save your fish in the case of a potential failure of your aquarium. Note: The basis for the information on the water change is the conductivity measured in the water of your aquarium. We therefore recommend calling up the current water change information at lunchtime, for example when CO2 fertilisation is in operation or after the water change and the addition of all components such as water conditioner and plant fertiliser.Features of the EHEIM aquaAlert+eWarning system with integrated WLAN function (Wifi) and wireless control via smartphone, tablet or PC/MacPrecise measurements of the aquarium through calibration Individual warning with customisable limit values  Alarm in the event of a sudden increase in conductivity >50 % within one hour) Multiple warning levels with corresponding recommendations for action  Colour-coded visual display of the warning level (green/ yellow/ red)  Automatic calculation of the time until the next water change based on gathered data history • Notification if the temperature is exceeded or the electrode runs dry  Reminder for electrode cleaning for permanently precise measured values; automatic

Compact, powerful and silent EHEIM compactON is the compact and yet powerful aquarium pump. Available in nine sizes, for flow rates from 170 to 16000 liters per hour. The EHEIM compactON aquarium pump is characterized by its name through a compact design and is thanks to the included accessory bag appropriate for versatile use – the EHEIM compactON 2100-5000 can also be modified for the use outside of the water. Thanks to the high quality material it is also possible to use them without problems in marine water. For even more flexibility, the flow rate is adjustable for all models, except for the EHEIM compactON 5000/9000/12000/16000. EHEIM compactON 300 is already appropriate starting from 170 liters per hour, EHEIM compactON 600 starting from 250 liters, EHEIM compactON 1000 starting from 400 liters, EHEIM compactON 2100 starting from 1400 liters and EHEIM compactON 3000 starting from 1800 liters. EHEIM compactON 5000/9000/12000/16000 is designed for a flow rate of 5000/9000/12000 litres per hour. Compared to the pumps of the EHEIM compact/compact+ series the power consumption was again improved by up to 50%. Also the delivery head is presentable and makes the pumps powerful enough also for the use in the filter basin. In order to guarantee a silent operation of the pumps, various measures have been taken like for example choosing a combination of ceramic axis and ceramic cover at the wing part of the EHEIM compactON 2100 and 3000.
