BioPlus Filtration

BioPlus & BioPlus Thermo internal filtration by Oase are designed for small to medium cold water or tropical aquariums.

There are six filters to choose from depending on the size and waste load of your aquarium. The number next to the filter shows the maximum amount of litres that the filter is designed for.:

  • BioPlus 50
  • BioPlus Thermo 50
  • BioPlus 100
  • BioPlus Thermo 100
  • BioPlus 200
  • BioPlus Thermo 200

BioPlus do not include a heater, but do have room to upgrade to a heater later on. BioPlus Thermo models do include a heater. For more technical data, please see the bottom of this page.

If your aquarium is more than 200 litres we have a full range of larger external filters in stock. These will handle more waste and turnover more water per hour, so that you get an even better flow.

Integrated Heater

This filter is an even better design than most, because it can house an aquarium heater, meaning there’s even less aquarium equipment visible in your tank. Having your heater installed into the filter unit also protects the heater, leaving it less exposed to the possibility of knocks or falling rocks or even of running dry.

If you click ‘yes’ to a heater, this filter will come with an Oase HeatUp heater installed. If you choose ‘no’ to the heater, a HeatUp can be added later on, and fits neatly into the filter. See below for details of the heater wattage needed. HeatUp by Oase is the only recommended heater for use with this filter.

Oase HeatUp heaters have internal thermostats in order to self regulate to the temperature that you set them to. They are fully controllable so that you can choose the ideal temperature for your tropical fish. Because the heater is situated within the filter, it works more efficiently. This is because there is a constant flow of aquarium water.

Magnetic Bracket

This filter is easy to clean because the magnetic bracket makes it easy to remove and attach the filter cartridges.

Space saving design

Place this filter discreetly in a corner of the aquarium for undisturbed views of your underwater world. The Thermo versions, have the heater neatly installed in the back corner of the unit.

Economical & efficient

The pump built into these filters is extremely quiet and energy efficient. The filter has a diffuser nozzle so that you can choose between a more standard single point of flow. However, you also have the option to choose a wide flow through the small holes at the top of the unit. This type of flow is similar to having a spray bar.

The BioPlus filtration range all include filter foams with high surface area volume, so that mechanical and biological filtration is effective.

BioPlus filtration is your aquarium’s life support system

When aquarium foam has a high surface area, more ‘friendly’ bacteria are able to colonise. This filter bacteria is denitrifying bacteria, which is excellent for dealing with ammonia fish waste. It is important to have a healthy population growing in your filter because it helps to break down fish waste.

Run an aquarium filter 24 hours a day to keep the water quality balanced for your aquatic animals.

In order to keep you bacteria colony healthy, remember not to clean your sponges with tap water. Chlorine in tap water kills off bacteria. So instead, take a small bucket of water out of the tank and gently squeeze your filter sponges in this bucket of water to remove excess waste. When topping up your tank afterwards it is important to use dechlorinator.
