Pool is a green/light green under the sun ( currently under a pool cover) its been forclosed on off and on since 10 been thru 3 owners so not sure what maintenance was done or if any during that time. Pool inground 14'w 30'l not sure capacity. It was built around 03-04 based on satellite pictures.
Should I start with:
Testing the water
Putting in the vacuum cleaner and letting it run for a day or 2
Drain pool and refill
Hire professional since I'm out of my expertise.
Thanks in advance for all the help
