Trusted by aquarists globally, the Aquael Ultramax BT delivers uncompromising water clarity for your most challenging aquascapes. Its innovative design combines patented engineering with intuitive app-controlled operation via Aquael BT, making maintenance effortless. Whether you're maintaining a freshwater showcase or a sophisticated marine setup, this premium canister filter guarantees the pristine water conditions your aquatic life deserves. Experience the difference that award-winning filtration technology brings to your tank.

Control your aquarium filtration from anywhere with the Aquael Ultramax BT—the next evolution in convenient tank management. Adjust power settings, flow rates, and operation directly from your smartphone or tablet using the intuitive Aquael BT app, available on both Android and iOS. Say goodbye to manual adjustments at the tank and embrace the freedom of remote management. Perfect for busy aquarists who demand both performance and simplicity in one sophisticated system.

Recreate natural aquatic rhythms with the Aquael Ultramax BT's revolutionary Day&Night scheduling feature. Program your filter to simulate realistic water movement patterns—faster during daylight hours, gentler at night—mirroring conditions found in open water ecosystems. Set feeding times with reduced flow to ensure your fish feed comfortably without water disturbance. This intelligent automation brings your aquarium closer to nature, promoting healthier behaviour and stronger development in both fish and plants. Experience filtration that adapts to your tank's biological needs throughout the day, creating the authentic environment aquarists have always dreamed of achieving at home.


The filter performance control is extremely simple and intuitive. You set the desired power level on your phone and the filter responds accordingly after a while. The control is infinitely adjustable – you set the appropriate percentage of filter power on the clear axis.

Choose from 4 flow modes such as constant, pulse, sinusoidal or intermittent and adapt the filter to the animals and plants in it. Different “ripple” modes allow you to simulate natural environmental conditions. This stimulates fish and plants to grow healthier and improves their living conditions.


The Ultramax BT filter allows the flow to be regulated as in open tanks, where the nighttime swell differs from the daytime swell. Simply enter the times you want the filter to run slower and the night mapping will take place. In addition, you can set a more moderate operation for times when fish are feeding so that they are not subjected to additional stress. The filter will begin to gradually reduce the flow rate so that it returns to the set speed just as gently when the feeding is over.

Experience engineering excellence with the Aquael Ultramax BT, built on patented innovations that set it apart from standard filters. Its expansive filter media capacity accommodates premium materials for superior water purification, whilst exclusive features—including an advanced prefilter, dual ball valve system, and self-filling mechanism—eliminate common maintenance frustrations.
