I noted small, elevated areas on the bottom of my abg pool 2 summers ago. At that time I couldn't figure out what was happening. Two years later, these have grown further into the pool and I figured out these must be tree roots. I have not noticed any leakage or lowing of the water level but think it is just a matter of time before the friction of brushing the pool and normal use from family playing in the pool will wear down the vinyl immediately above these roots. Other than cutting down the trees, which unfortunately are not on my property or digging around the perimeter of the pool to sever the roots, any suggestions to avoid the inevitable of needing to replace the liner, at which time the roots could be removed, but I assume will return. I have not seen this issue addressed before. Thank you in advance for any help.
