Glad you got it patched!

If both patches were properly applied, it shouldn't be leaking there anymore. However, if the liner failed in one place, who's to say that there isn't a smaller hole somewhere else? If the water loss is negligible, ignore it - if it's bothersome, do some serious leak detection and dye testing.

I'd use a round rock (~ the size of the patch) to mark the area to avoid. I wouldn't let anyone step near the rock and certainly wouldn't vacuum within 5" of the rock. I would dive down and pick up the rock every other day and gently rub the patch, to keep algae from growing under it.

If you are SURE that you'll be replacing the liner next spring - I'd skip using any extra chems when you close the pool - who cares if it's a swamp when you open the pool -you're replacing the liner and water?

One last thing, can you tell me about your vacuum?

I hope you will enjoy the rest of the season with your pool
