Oase BioMaster External Filters
The ultimate convenience among the external filters for aquariums. The external filter meets the highest demands in water filtration and filter cleaning. The combination of highly effective biological filtering with Hel-X and mechanical/biological cleaning with filter sponges ensures healthy and clear aquarium water. The BioMaster is suitable for aquariums with a volume of 250 to 600 litres. No complete cleaning needed: the EasyClean pre-filter chamber enables convenient filter cleaning. The automatic shut-off and safety lock prevent unwanted water leaks, e.g. when removing the pre-filter module. A practical venting button makes the water suction highly effective and allows for a quick and convenient start. The complete set includes filter media, hoses, adapters, suction and discharge pipes as well as the water diffuser. The BioMaster is available with or without an adjustable heater.
Features:
External Aquarium Filter - For the Highest Demands
- EasyClean pre-filter module – Module can be removed separately from the rest of the filter. This reduces maintenance, increases filter efficiency, and extends the life of main filter foams. Customize the pre-filter with coarse 30 ppi, fine 45 ppi, ultra-fine 60 ppi, and activated carbon 45 ppi filter foams
- No mess maintenance – Integrated safety locking features on the handle, pre-filter, and check valve in the inlet/outlet connection unit, ensure no accidental spillage or messy maintenance
- Sealed filtration pathways – Allows for the full benefits of all four stages of filtration through this intuitive design
- Hel-X Biomedia – An extremely large protected settlement surface (800m²/1000 liter) that allows beneficial bacteria to grow and thrive. The material is designed to stop floating as soon as it reaches a certain level of bacteria colonization.
- Carbon pre-filter foams – Activated carbon absorbs unwanted substances in aquarium water. Carbon filter foams make replacement much simpler than using common granular carbon.
- Adjustable flow control – Flow can be adjusted for the inlet and outlet in multiple locations on the filter assembly
- Easy priming – Includes simple priming for fast and easy startup and continued operation
- Quiet operation – Sound dampening design
- Heater integration capability - Easily integrate an OASE HeatUp adjustable heater into the BioMaster canister (HeatUp not included)
- What’s in the Box - Aquarium Filter, filter media, intake tube with inlet strainer, water distributor nozzle, spray bar, inlet and outlet adapters with flow control, tubing, fittings, heater adapter, and power cable
- Made in Italy, backed by German engineering
- Fresh and marine water compatible UL certified filter
- 3 year warranty plus 1 year warranty extension with online registration

WYSIWYG Corals
All corals in the Coral section of the website are WYSIWYG corals (What You See Is What You Get). These corals are photographed on egg crate, with each egg crate square measuring approximately ¾” or 2 cm.
Coral Frags
All Coral Frags are mounted and then quarantined in our facility for at least 60 days prior to selling. Coral Frags are not WYSIWYG, unless otherwise stated. We will choose the biggest and healthiest pieces that we have in stock.
Coral Acclamation
To properly acclimate your coral pieces to your aquarium environment, float the coral in your aquarium while it is still inside of the shipping bag, for approximately 20 minutes to bring the coral to the same temperature as the aquarium.
Open the shipping bag and pour the water and into a small shallow container, something like a Tupperware container and gently place your coral into this water. Add some of your aquarium water to completely cover the coral.
Gently remove any debris from the coral. We recommend the use of a small baster. It is very important to be gentle during this process!
When first adding corals to your aquarium, we recommend putting them at the bottom of the aquarium so that they can easily adjust to new lighting conditions.
Use super glue or epoxy glue to adhere your new coral to its new home. Make sure that the coral is secure to prevent it from being dislodged.
Keep an eye on your new coral. Look for signs of stress. Often, it takes a few placements to get your coral in its ideal long-term location.
