Pool Calculator and Pool surface

[tollgate]

My pool is tiled concrete, but the pool calculator does not offer this surface as an option.

What is the best option to choose?

Plaster, as the grout has similar chemical concerns.

Concrete also has calcium carbonate (it's made from cement). It's not just grout or smoothed pool plaster (which contains cement as well) over gunite. In some sense you can consider concrete to be the same as pool plaster except that pool plaster uses different aggregate to be white (and the mix proportions might be somewhat different).

Plaster it is then. Thank you both.
