Hi all and thanks in advance for any input! I've recently poured a 10'x10' concrete slab in preparation for delivery of my very first hot tub next month. Unfortunately, the finished slab has a low spot which is just less than 1/4" at its deepest point. The two photos below show the area that I'm describing; one of the photos is a close-up of a 2x4 standing at the deepest point of the low spot. Importantly, I would note that the entire ~6-inch perimeter around the slab is just about perfectly level. The question is whether this imperfection in the slab requires remedy, or if I'm dwelling on a non-issue. If it's a problem, how would you go about fixing it? Self-leveling concrete? Thanks again.

Does anyone have any experience with this? We've been told that the fill line likely has a crack and roots from the ground are growing inside of it. The roots are small little white roots. The roots plug up the fill line and the pool will not fill. However, we are not leaking water, no huge water bills. Has anyone ever fixed this problem? Will we have to dig up the concrete pad to get to the fill line & repair it? We are trying to find the least expensive way to deal with this problem. Thank you for any insight & help!
