Hey -

I started to level my pool, and have this one spot that is "spongy". I step on it, it sinks, then I move and it comes back up. I thought there was a monter in there so I put a 12" nail and nothing came out If I can shove a nail in the ground with my hand that can't be good.

The spot is 1x1ft.

Should I dig it up? It would be near one of the corners in my 15x30 oval pool.

Thanks,
Brad
