Key Product Features

Filtration

Each model includes multi-stage filter cartridges and biological filter foams to ensure optimal water quality and clarity.

The number of cartridges and foams inside the unit depends on the filter size.

Easy Installation

The adjustable leveler foot helps secure the filter to different aquarium glass thickness.

The transparent telescopic intake tube extends from 6 in. to 14 in. for varying aquarium heights.

Adjustable Flow Control

Built-in to the filter to change the intensity of water movement and increase oxygenation, or input of oxygen at the surface.

Easy Maintenance

When the Cleaning Indicator is fully visible the cartridges and foams need to be checked, and cleaned or changed.

Integrated Heater

Reduces the amount of equipment seen inside the aquarium. Provides uniform and consistent temperature of ~79˚F. Thermo models only (coming soon).

Color Options

BioStyle 20, 30, 50 are each available in 2 colors: navy and white (grey coming soon).

Quality Design

Made in Italy, with German engineering from OASE and backed by a 3-year warranty.


How it Works

1. Water is pulled up through the intake and into the filter.

2. The water flows through the filter chamber that houses the multi-stage filter cartridges and biological filter foams. The water circulates through the different filter media which collects debris and provides optimal water quality and clarity.

For thermo models, the water is simultaneously being heated by the integrated heater.

3. The clean, clear water exits out of the BioStyle and back into the aquarium via the spillway.

BioStyle Filter Media

All BioStyle models come with multi-stage filter cartridges and biological filter foams. OASE offers additional chemical media cartridges that can be added to the BioStyle filter based on your aquarium needs. OASE also offers an empty cartridge for further optimization.

Multi-stage Filter Cartridge

Comes standard in all BioStyle models. Disposable cartridge houses 3-stage filtration.

45 ppi Filter Foam: Traps debris and waste and also offers surface area for beneficial bacteria.

Three chemical media mix: Carbon, zeolite and phosphate binder. Removes odors, impurities, and harmful nutrients from the water.

Filter fleece: Traps extremely fine debris for a water polishing effect.

The filter cartridge should be replaced after 4-6 weeks, depending upon aquarium size, number of fish and plants, and declines in filter performance.

Replacement cartridges are available in a 2-pack and a 4-pack.

Biological Filter Foam

Comes standard in all BioStyle models.

Traps debris and waste and also offers surface area for beneficial bacteria to settle. This mechanical and biological filtration results in cleaner, healthier water for your aquarium inhabitants.

This 30 ppi filter foam should be replaced after 12-18 months, depending upon aquarium size, number of fish and plants, and declines in filter performance.

Replacement foams are available in a 2-pack and a 4-pack.


Additional BioStyle Filtration Cartridges

To optimize your aquarium filtration, OASE offers different filter media cartridges based on your aquarium needs. These cartridges fit into the BioStyle filter chamber, in place of the biological filter foam. The quantity of cartridges the filter chamber can fit depends on the size of the BioStyle filter.

Activated Carbon Cartridge

Helps to remove cloudy water, harmful metals, odors, tannins or other colors for clear, pure aquarium water.

Activated carbon is processed to have small, low-volume pores that increase the surface area available for absorption of unwanted substances.

Carbon should be used only when needed and replaced after 3 to 4 weeks, depending upon aquarium size, number of fish and plants, and declines in filter performance.

Phosphate Binder Cartridge

Strong, fast acting buffer that reduces phosphate levels to solve algae problems. This is done by quickly and permanently binding phosphates so they can’t return to the water.

The bead-shape is highly porous to promote easy flow through, increasing efficiency and capacity. Free of heavy metals, Phosphate Binder is colorless and will not cloud the water.

Phosphate binder should be used only when needed and replaced after 2 to 6 weeks, depending upon aquarium size, number of fish and plants, and declines in filter performance.

Customizable Cartridge

Add your choice or combination of dry, solid filter media into this empty cartridge based on your aquarium’s needs; filter media sold separately.

The customizable cartridge inner capacity is 120 mL with dimensions of 0.57 x 2.3 x 5.8 inches.

Timing to replace the cartridge depends on the media you put inside and depends upon aquarium size, number of fish and plants, and declines in filter performance.
