For a Doughboy filter, it's best to use filter sand that is specifically graded for pool filtration. This sand is typically silica sand with a grain size of 0.45 to 0.55 mm. Avoid using play sand or other types of sand, as they may not filter the water effectively and can lead to clogs or reduced filtration performance. Always check the manufacturer's recommendations for the specific sand type compatible with your filter model.
