## Description

The OASE BioMaster 2 350 is the next generation of our best-selling BioMaster filter—reimagined with updated features, making it our most efficient and user-friendly filter yet. The OASE BioMaster 2 delivers advanced, quiet, and user-friendly external filtration for freshwater or saltwater aquariums. With curved inlet/outlet tubes and adjustable flow control, it offers optimized circulation and performance over earlier models. Its EasyClean pre-filter module removes separately, reducing mess and extending the life of your main filter foams. Priming is simple, and the detachable aquastop allows for easy maintenance without disturbing tubing. The BioMaster 2 uses a 4-stage sealed filtration path that includes fine and coarse foams, activated carbon, and Hel-X Biomedia for superior mechanical, biological, and chemical filtration. Though it doesn’t include a built-in heater, it’s designed to easily integrate the OASE HeatUp heater—reducing in-tank equipment and protecting aquatic life from direct heat exposure. High-quality materials, robust impeller, enhanced ventilation, and rubber feet that dampen vibration, all allow the filter to run quietly. Safety locks and spill-free design make it easy and clean to maintain. Ideal for aquariums up to 90 gallons, the BioMaster 2 is Italian-made, German-engineered, UL certified, and backed by a 4-year warranty (3 + 1 with registration).

Review: Great canister filter - This is a great filter with built-in heater. It is easy to service and is well made. It has great filtration capacity, good instructions, and plenty of replacement parts. I has more than enough filtration capacity for my 40 gallon tank. I turned it down to about 50% of capcity, so that the outflow isn't too strong.
Review: Very good filter! Will purchase again for future setups. - Absolutely works as designed. In fact, I've noticed it causes less water evaporation than every other filter I've ever used for my 75 gallon setup. Totally quiet. Easy to install. It is heavy to move around when water is in it but that is the weight of the water. Would definitely purchase in the future for other setups. Worth the cost for everything it provides. Very sturdy.

### ⭐⭐⭐⭐⭐ Great filter.
*by A***R on February 7, 2026*

Love the prefilter on this design. The dock for the in and outflow was a little sticky, but they called that out in the packaging and included a QR code on a video to help with it. The filter is easy to use and service and tightly made. The free bar outflow and inflow and sponge media were never in the cards for me, since I prefer glass lily pipes and other filter media, but it has everything needed to make it work out of the box.
