distinguish between slow and rapid sand filter
No, sharp sand and pool filter sand are not the same. Sharp sand, also known as concrete sand, has larger, angular particles and is often used in construction and landscaping. Pool filter sand, on the other hand, is specifically graded silica sand designed for use in swimming pool filtration systems, providing effective filtration due to its uniform particle size and smooth texture. Using the wrong type can affect pool water clarity and filtration efficiency.

If you have a sand filter the laterals in it may be starting to show signs of wear these wil blow sand from the sand filter into the pool when they wear out.
General purpose sand is not recommended for use in pool filters, as it may not be the appropriate size or shape for effective filtration. Pool filters typically require specific types of sand, such as silica sand, which has a uniform grain size and is designed to trap debris efficiently. Using the wrong type of sand can lead to poor filtration and potential damage to the filter system. Always consult the filter manufacturer's guidelines for the best materials to use.

Im not an expert by any means but what I know is that with a sand filter system if your pump is not the corect HP for the filter it will push dibris and sand right back into the pool answer:: That may be true in remote cases where the system was not installed correctly or had well balanced/matched equipment. The correct answer would most likely be that you have a broken lateral(s) which allow sand to pass back to the pool. It is best to find the correct type lateral for your specific filter. Some manufacturers have made modifications to same model filters as production and technology progresses. Replacing the lateral required turning the equipment off and making sure it will not come back on while it is being worked on. Removing the filter top or valve assy. Removing all sand, finding the damaged lateral(s), replacing lateral, replacing the sand with new sand in the correct manner, replacing the valve or filter top and starting the equipment and backwashing the filter to reduce the dust blow back K
