OASE BIOMASTER

  • EasyClean pre-filter chamber for extremely simple filter cleaning and top comfort
  • Available with or without integrated HeatUp adjustable heater for undisturbed views of the underwater world without visible technology, optimum temperature level, improved safety
  • Perfect water quality thanks to the high filter volume consisting of Hel-X and filter sponges

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

Features

Ventilation slots

Ventilation slots in the lid of the filter and aeration grooves in the outflow ensure that water returned to the tank is fully oxygenated and maximize gas exchange during filtration.

Bottom-to-top flow

The pump pushes water up into the basket of the filter, entering through the bottom of the basket and being pushed out the top. A bottom-to-top flow ensures that water comes into contact will all filter media, and cannot go around or over filter media as with hang on back filters with a back-to-front flow.

Maintenance alert

Over time, filtration media can become clogged with detritus reducing or obstructing the flow of water through it. When this happens in Tidal™ filters, water is redirected around the filter and back into the aquarium through an outlet on the side. The redirected water pushes up the blue maintenance alert on the top of the filter, signaling that the filter needs to be cleaned.

Surface skimmer

The surface skimmer will capture the water from just below the surface, where excreted fish oils accumulate, as well as deeper in the tank removing floating debris

Telescoping intake pipe

The adjustable telescoping intake allows water to be taken from any level of the tank without the need to stop the filter or bother with spare parts

Flow regulation

The flow on the pump is adjustable using the dial on the front

Intake flow regulation

A dial on the side of the filter adjusts how much flow comes from the underwater intake versus the surface skimmer

No filter cartridges

The filter basket has a huge capacity to hold filtration media of your choice in the configuration of your choice. All Tidal™ Filters come with Seachem's Matrix™ bio-media to get you started.

No mess maintenance

The basket is fully removable and snaps into the lid of the filter for easy and drip-free transit to a sink or hose for cleaning.

Self-priming pump

Self-priming pump means there is no need to fill the filter basket with water, start a siphon, monitor the filter, or any of the other headaches of starting a new filter

Self-cleaning impeller

The self-cleaning, corrosion-resistant impeller is suited for both saltwater and freshwater environments. This cuts down on maintenance and makes the filter suitable for a wide range of environments.

Adjustable leveling device

A leveler on the base of the filter lets the filter adjust to a variety of aquarium styles

Heater holder

A heater can be attached to the side with an optional heater clip, allowing for better dispersal of heated water through the aquarium.

3 year warranty

All Tidal™ Filters are guaranteed against defects of materials and workmanship for a period of 3 years from the date of purchase, except for the pump’s impeller. This can be extended to 5 years by registering your filter. The warranty covers the replacement of the defective parts.

Overview

PhosBond™ is a revolutionary new product that combines the phosphate removing capabilities of both aluminum oxide and granular ferric oxide into a singular material forming a synergistic effect. It rapidly removes phosphates and silicates from saltwater and freshwater, combining the best of both types of phosphate removers. Its high porosity and surface area give it a large binding capacity, while its physical strength and integrity assures that it will not break down from mechanical stress.
Comparing Seachem Phosphate Removers
Product PO4 bound
PhosGuard (Alumina Oxide) 0.87 mg/g
PhosBond (GFO and Alumina Oxide hybrid) 1.19 mg/g
PhosNet (GFO) 1.41 mg/g

Directions

For best results, PhosBond™ should be rinsed before use and placed so as to maximize the flow of water through it but not so that it tumbles against itself in flow. It may be used in a canister filter, media chamber, box filter, or any high flow area of a trickle filter. Use of a filter bag such as The Bag is recommended. Use 60 mL (1/4 cup) for every 200 L (50 US gallons) saltwater or 400 L (100 US gallons) freshwater. Leave product in place for 4 days, then test phosphate or silicate concentrations with either MultiTest™ Phosphate or MultiTest™Silicate. If the concentration of the component you are trying to decrease has not dropped to around 0.02 mg/L, then replace the PhosBond™, otherwise leave in place until levels begin to climb again. As long as concentrations remain under control, the product is not exhausted. Over treating is not recommended. PhosBond™ is not an exchange resin and does not release anything into the water. It does not leach phosphate or silicate back into the water and may be removed, dried, and returned to service until exhausted. Continuous use of small quantities is better than intermittent use of larger quantities.
The Bag™ is an innovative welded filter bag with a durable non-stitched seam. It has a 180 micron mesh, is resistant to bleach, caustics, and acids, and comes with a convenient resealable locking closure. It is available in a convenient 5" x 9.5" size. It is ideal for all filtration products and has an exceptionally long life. Unlike stitched seams, welded seams are not subject to degradation from exposure to bleach, caustics, acids, or other harsh environmental exposure likely to take place during regeneration of filter media. Caution should be excercised, however, to avoid overfilling or over-packing as welded seams can be forced to separate by excessive pulling forces. Sizes: 13 x 25.5 cm (5” x 9.5”)

The Bag

  • Dimensions 13 x 25.5 cm (5” x 9.5”)
  • Mesh Size Superfine (180 Micron)

Directions

  • Customisable temperature: HeatUp adjustable heater available as an option for FiltoSmart Thermo – also easy to retrofit using ThermoFit for FiltoSmart
  • Effective: Large filter surface in a compact size
  • Automatic shut-off: No unwanted water leaks during filter cleaning
  • Easy to open: Easy-click opening mechanism
