Hi, I am new to this site, I found it while I was searching for tips, but I seem to have come across what I think is a problem. This is going to be my 4th year closing my pool and have never had a problem except for the occasional rip in my cover, but this year after investing in season tickets to my favorite football team and the season starting with work i kind of neglected my pool for a few weeks. I finally had a day off and I vacuumed my pool that had lots of stuff on the bottom, i have a vinyl abve ground pool. when i was vacuuming i noticed that a lot of the algea was stuck, staind, or grown into the bottom of the pool. I shocked my pool and fixed the ph, which seemed to help a little, but i was wondering if it is bad to close my pool like this or should i fix this now? but overall i am kinda lost on what to do.
any help would really be appreciated.
