Very new to the pool world. Have a 24 ft above ground pool and was trying to vacuum for the first time. I have a salt water system and with the vacuum still in skimmer and the filter still running, I switched to backwash. When I switched back to filter there was a green substance flowing out of the return fitting. Now my pool is a cloudy green. What is it and what do I do? Thanks
