This creates a healthier and crystal clear swimming environment with the added benefit of therapeutic minerals.



The smooth surface of Theraclear Glass Filtration Media provides supreme water flow through your filter tank, which creates better hydraulic water recirculation through your entire swimming pool. The better the hydraulic performance of your pool system the less work your pool pump has to do, this will allow your pool pump to have a longer life expectancy. As this product provides better flow through your filter tank it reduces your backwashing frequency, this means that it saves your water usage and reduces your pool chemical wastage saving you money.
