Pool sands are not created equal. Red Flint Pool Filtration Sand is made to the same exacting standards as potable water. Red Flint is the cleanest and most durable pool filtration sand you can find in North America. Effective in removal to 10 microns in our standard .45 to .55 mm size. Our standard .45-.55 Pool Filtration Sand is effective for residential and commercial applications. With proper filter operations Red Flint Pool Filtration Sand will be the most effective and durable filtration media you can buy.

For tougher commercial applications, or even for home use you could consider a Garnet Layer. This heavier weight media at a finer size will do additional particulate removal to 5 microns should your application require this. Most residential applications do not need this level of particulate removal and get required functionality with Red Flint Pool Filtration Sand as the only required media. You will need to check the filter manufacturers specifications to ensure a Garnet layer will work. Depending on your filter you may have the capacity to layer media in the filter. If this is the case, our Garnet product can be a layer under the filtration sand. The result will be removal down to 5 micron. This all natural combination is often more economical than other more expensive media alternatives that claim to remove particulate to 5 microns.

Whether your needs include standard products or something not attempted before in Sand Media processing, Red Flint Sand & Gravel will Deliver optimum project results with respect to your Sand Media requirements.
