Very important step to keep your sand filtration running peak performance is to change the sand. Pool filter sand often becomes “mudballed” containing small clumps of oily gunk, or it may become “channeled”, which is when water has worked open holes in the sand and is streaming right through (without really going through the sand). In hard water areas, it can “calcify” with calcium deposits, literally turning the filter sand to sandstone. Other water balance problems or an oversized pool pump can also contribute to pool filter sand deterioration.
Many years of forced water wears away the sharp edges of pool filter sand. Over time, the sand grains become more circular, losing their sharp edges, and their ability to trap small particles.
General rule of thumb is to replace sand every 5-7 years. Pool sand filters are known to be the lowest maintenance of the three types of pool filters. Sand filters are the easiest to operate and maintain.
