My liner got a tare and needed to be replaced. Dummy me, instead of waiting, drained the pool and removed the liner (it was getting full of mosquitoes). Now, I have an empty pool. However, now that the liner is out, I've noticed that there are several small cracks in the pool base (water is seeping in) and uneven areas that appear to be from groundwater pooling under the liner and eroding away the base. How bad is this and what are my options here? HELP!
