Hello Everyone,

Your support is greatly appreciated.

My pool was built in Nov. of 2021 in Cincinnati Ohio. Its a 20 x 40 inground with liner. I have used the pool for 1 season in 2022, and now into 2023. This year I found that the vermiculite is soft where it meets the steel wall in the shallow end in-between a light and return skimmer. I can push with my foot down and feel the give and probably push it further if I wanted, but was concerned. I would say it feel similar to sand or clay underneath the liner. I'm hoping someone could shed some light on my situation. How concerned should I be? Why is this occurring? What can be done about it? Would a leak at the light or skimmer create the problem? So many questions.... The worst area is in-between both skimmer and light, with about 5" from the wall being soft, as you move toward the skimmer it reduced to maybe 3". I didn't notice it last year, but not saying it wasn't there, just didn't do a check.

I'll be doing a bucket test this weekend to see if the pool is leaking, but wasn't sure if this would cause the situation.

Thanks!
