Is your water full of algae or debris?
Yes lots of algae also noticed sand after backwashing on ground
That would explain the frequent need to backwash. The filter is catching stuff. So, it is doing its job. Might be a good idea to post a current set of water testing results taken with a drops based kit for us to take a look at.
Thanks is it normal to lose the sand out of filter when back washing
It is normal to lose a small amount of sand when backwashing.
