I am considering a 18x34x52 AGP with a expandable liner to 7'. I live in the Hampton roads area of Va about 50 miles from the ocean. I have watched youtube videos on installing them but my questions is for the deep end section, what are people doing about ground water coming up under the deep end. Will it create bubbles or pockets of water underneath? Or is there enough downward pressure from the pool being full to not cause this? Or am I just overthinking this? Thanks for any responses.
