The Biotop System
The Biotop Natural Pool filtration system has been developed and refined over the last 25 years. The system is based on the constant circulation of water from the swimming area of the pool and down through specially graded chemically inert grit. As the water travels down through the grit any organic material and nutrients are trapped and broken down by the mix of plants growing in the grit. This combination of mechanical and biological filtration provides perfect water clarity.
