I have a vinyl in ground pool i keep having to add water every other day im pretty sure i have a leak some where can someone please help me also i see sand in the bottom of the pool pool. does anyone no any tricks on how to find a leak thanks

 

I have not worked on a pool in some time and these were almost always concrete pools. However my first suspicion is the filter. Watch were your water level ends up after a few days. If its stays steady below the filter level you probably loosing water from that intake connection or a return connection.

Just something to try.
