The most effective type of pool filter is Diatomaceous Earth or D.E. Filter. It works by sifting our pool water through its series of grids inside the tank. The grids filtering element is the layer of D.E. powder. If running your filter system and you notice this powder is in your pool then you may have a torn grid or multiple torn grids. If this is the case, follow this "How to", step by step, to get your filter back up and running.
