Pool is leaking

[jeffc]

I have a 24' round pool. I am a new pool owner so I am not entirely familiar with this pool yet. I recently filled my pol with water and everything seemed good. Then I noticed a big air bubble in the bottom of the liner. I think it was because the bottom drain wasn't sealed properly so I fixed that. It didn't stop the leak though. My pool water just keeps going down and down and my yard around the pool is wet and soggy I'm not sure what to do now. Any help and advice would be greatly appreciated. Thank you
