OASE BioStyle is a sleek, compact power filter, ideal for marine and freshwater aquariums up to 30 gallons.  The BioStyle Thermo 30 contains two disposable, multi-stage filter cartridges and two 30 ppi biological filter foams for increased biological and mechanical efficiency. Each complete Multi-Stage Cartridge houses a 45 ppi foam for mechanical and biological filtration, a chemical mix to remove odors, impurities, and harmful nutrients, and finishes with a filter fleece for a polishing effect. The easy to see cleaning indicator shows when it is time to change the mess free, disposable multi-stage filter cartridges or clean the biological filter foams. The filter includes two additional 30 ppi Biological Filter Foams that traps debris and provides even more surface area for beneficial bacteria growth. To further customize your aquarium filtration, OASE offers additional chemical media cartridges that can be added based on your aquarium needs. BioStyle filters are designed for easy installation, with an adjustable leveler foot for securing the filter to different thicknesses of aquarium glass and with a telescopic intake for varying aquarium heights. The filter’s built-in adjustable flow control allows you to change the intensity of water movement in your aquarium and increase oxygenation, or input of oxygen at the surface. This BioStyle Thermo filter reduces the amount of additional equipment seen in the aquarium by integrating a heater into the filter unit. The heater has a set temperature of ~79 °F. Designed with German engineering and manufactured in Italy, this quiet and energy efficient filter is backed by a 3-year warranty.

  • COMPACT, SLEEK POWER FILTER WITH INTEGRATED HEATER – Quiet, energy-efficient hang on the back filter is ideal for fresh or marine aquariums up to 30 gallons.
  • BUILT-IN HEATER - Reduces the amount of equipment seen inside the aquarium by housing the heater in the unit. Also protects aquarium inhabitants from coming into direct contact with the heating unit. The heater’s pre-set temperature is 79°F.
  • CLEAN, CLEAR, HEALTHY WATER – The included multi-stage filter cartridges and filter foams clean on all mechanical, chemical, and biological levels of filtration for a truly healthy aquarium. The equipped cleaning indicator visually shows when it is time to replace the mess-free, disposable cartridge or clean the filter foam. This filter includes 2 multi-stage filter cartridges and 2 biological filter foams.
  • ADJUSTS TO YOUR AQUARIUM – Features include a leveler Foot for securing filter to different aquarium glass thickness and a telescopic intake that extends from 6 in. to 14 in. for varying aquarium heights. A built-in adjustable flow control allows you to precisely change the intensity of water movement.
  • QUALITY DESIGN – Made in Italy, with German engineering from OASE and backed by a 3-year warranty.
