We got an above ground pool this summer and our installer messed up on our vinyl liner install and had to come out and replace it a few days ago. We just finished re-filling the pool and now I'm left with questions. Now that temps are lower here in buffalo, it seems like a reasonable time to close the pool. The installer told us to fill to just below the skimmer, throw in a bottle of shock and close it up. The store basically said the same thing but recommended a few winter chemicals also. But I called another pool store and they said we absolutely need to fill to top, run the filter and get water balanced (specifically with calcium) before closing. At this point we did decide to fill to the top and get the filter running but aren't sure what to do now. This is our first season with the pool as is, so it's all new to me. Any advice?
