Hailea BT Internal Filter

Description
Internal submersible filter with aeration system.
Hailea HL-BT filters are equipped with a spray attachment that regulates the flow through the filter and thus oxygenates the water level in the aquarium.
Reinforced ABS original particles to shape the case that never wears out.
High quality resin to seal the winding and never leak electricity.

2 stages of filtration:
Biological- by converting organic compounds containing nitrogen into nitrides and subsequently into nitrites, it creates colonies of beneficial bacteria.
Chemical- activated carbon with a special structure that better releases impurities in the water.
