Dophin Sponge Filters

Dophin Sponge Filters

Dophin Sponge Filters are air-driven biological aquarium filters for hobbyists who keep fish or raise fry. They give your tank a simple biological filtration system with a sponge that can be replaced regularly.

Key Benefits

• Biological filtration system for freshwater aquarium set-ups
• Suitable for aquarium fish and for fish fry
• Wide range of use, from community tanks to breeding and fry tanks
• Replaceable sponge, so the filter can be kept in service by renewing the sponge regularly
• Circulation is supplied by an air pump connected to the filter

How to Use

• Connect the filter to an air pump. The pump supplies the circulation pressure the filter needs to work.
• Replace the sponge regularly to keep the filter performing.

Suitable For

• Aquarium fish
• Fish fry

Compatibility

These filters must be connected to an air pump to operate. Circulation depends on the pump, so flow stops whenever the pump stops, for example during a power cut.
