Supplied without slider (pump always runs at full power). Thanks to its small dimensions, the submersible pump can be installed in the smallest of spaces. The installation is conveniently carried out using suction holders.

5. Eheim Aquarium regulator heater
Obvious ideas are often the best. For example the aquarium heater as a rod. The heating element is simply hung in the water and heats it. It is true that the principle is still the same as decades ago. But a lot has changed in the meantime. And today the adjustable Eheim heating is a state-of-the-art electronic heating device with the best available technology. A jacket made of special laboratory glass enlarges the heating surface, serves as a heat shield and ensures optimum, even heat emission. And regardless of whether you want to heat a 20 or a 1000 litre aquarium - you have 9 sizes to choose from.

6. Eheim Air pump set 3701
There are three models with pump capacities of 100, 200 (2 x 100), and 400 (2 x 200) l/h, with the smallest model having one and the two larger models each having two separately adjustable air outlets. Accordingly, one or two Eheim diffusers are included in the delivery.
The air volume can be adjusted directly on the device for each air outlet, as well as at each diffuser. This allows you to customize the bubbling effect according to your taste and needs.

7. Eheim Air pump set 3704
The vibration-damped Air Pump 400 from EHEIM has a pumping capacity of 400 (2 x 200) l/h and features two separately adjustable air outlets. Therefore, two diffusers are included in the delivery. The air volume can be adjusted directly and manually on the device for each air outlet. Additionally, adjustments can also be made at each diffuser. This allows for the bubbling pattern to be varied according to taste and need. The pump's quiet operation is further enhanced by vibration-damping rubber edges. This keeps the air pump stable and prevents it from moving around unintentionally. The characteristic hum of a classic air pump is also minimized. A special tab is provided for wall mounting. It is also ideal for operating air-driven sponge filters or a bottom filter for shrimp aquariums.

8. Juwel Aquarium Eccoflow
All Eccoflow pumps feature double-bearing impellers that are specifically matched to the respective motor power. This ensures the exceptional smooth operation and low power consumption of Eccoflow pumps. With separately available ceramic shafts, Juwel Eccoflow pumps are also ideal for use in saltwater. The bypass principle ensures continuous and automatic cleaning of the impeller chamber. Of course, Juwel Eccoflow pumps meet the highest safety standards and are TÜV/GS certified.

Installation is conveniently done using suction holders.

Turn the pressure control fitting with internal thread onto the external thread (M10x1) of the storage cylinders.

The total height with the mounted pressure reducer is 37 cm.
