New homeowner that came with pool.(Previous owners did not open it since 09. Short sale home) So far, it's been a nightmare. I had a company come in 3 times now and they seem to do the same thing. Throw some shock and chlorine tabs and call it a day. They refuse to vacuum the bottom of my pool, because the debris is too thick and they are scared to drain too much water on waste since it's a vinyl pool. Any suggestions about vacuum techniques on vinyl pools? The water is green and cloudy right now.
