OK.

But long term, a covered, unused pool is a risk. Bad things happen when people or pets fall unexpectedly onto a pool cover.

I'm not sure how to advise you.

1. With a damaged liner, it's hard to keep water in the pool.
2. Without water, there's great risk of pool wall collapse.
3. Any sort of tarp & tent cover will require regular maintenance, one way or the other.

I just don't know of a really good way to close pools long term, that doesn't involve removing or filling them.
