I have the shells, and I can't tell they make it any rougher. There are a few places in my pool where there doesn't seem to be any shells. It feels the same as where there are.
They are tiny like a flake of baby cereal or the smaller flakes of aquarium fish food. I swim under water with a mask on - a lot - mine are flat, different from the pebbles.
I LOVE them!
