Streamax 450 – cascade filter for aquariums of 38–76 litres

The Streamax 450 is a cascade filter for hobbyists keeping aquariums of 38 to 76 litres who want to place the filter outside the tank and save space inside it. The water return through the cascade aerates the water, and the unit combines biological, mechanical and chemical filtration in one housing.

Why it matters

• External placement: the filter sits outside the aquarium, leaving the interior free for décor and livestock. The return cascade also aerates the water.
• Adjustable flow: flow is regulated steadily between 225 and 450 l/h, and the intake tube length can be adjusted to fit different tank setups.
• Three-stage filtration: a high-porosity media cartridge hosts bacteria that reduce NH3, NH4 and NO2 levels, a nonwoven fleece removes particulate matter, and activated carbon binds metals, humic substances, pesticides and metabolic byproducts while reducing odour.
• Replacement alert: a built-in sensor signals when the filter media needs replacing, so routine manual checks are not required. Replacement cartridges are sold separately.

What it works with

The filter is dedicated to aquariums in the 38 to 76 litre range and suits both freshwater and, according to the manufacturer, seawater setups. Its 225 to 450 l/h flow range makes it usable across tanks of this size, with the intake tube length and flow regulation allowing the output to be matched to the specific aquarium.
