I mean, it's only the pure water that evaporates, right?

It's not the evapuration part of the equation that's the problem -- it's the water that your gel (or beads) are sitting in. The imurities and spores in some tap water (even chlorinated water) can cause mold (or algae, moss, etc.) growth in your media (gel in this case).
