Clean water through a filter, filter material and microorganisms that are perfectly balanced with each other - the sera biological filter system.
Long-lasting crystal clear and biologically pure water with a new bioactive filtration system with an integrated UV-C system!
UV-C system (5 W) - reduces algae growth and destroys pathogens in the aquarium.
Benefits and advantages:
Unrivalled price/quality ratio
Reduced algae growth and unwanted diseases
Immediately ready for use, easy to start up and easy to maintain
Low energy consumption, quiet with a long service life
Fast and effective breakdown of ammonium/ammonia and nitrites
With serafilterbioactive you get: sera biostart 50 ml. and seraSiporax® 1 l. (2 l for sera fil 400 model)
Biologically active filters with sera filter biostart (added directly to sera Siporax®). Contains the right microorganisms in the right combination for a perfectly balanced filter.
As soon as you add the microorganisms to the highly porous structure, they settle on a surface of 270 sq.m per 1 liter and sera Siporax® is already biologically active. Its surface area is 34 times larger compared to ordinary filter material.
Greater porosity per liter does not bring additional benefits, as this means smaller pores unsuitable for bacterial life! The active filter allows for rapid stocking of the aquarium with fish.
