Firstly,
water fountains need a lot of feeding water because they lose huge amounts of water due to evaporation. Where water evaporates limescale is left behind and eventually settles. The water quality and the design of the fountain determine where the deposits form. They can either be visible in the whole basin or just in the spray nozzles.
Secondly,
not only limescale is a problem but also algae growths excellently. Depending on the environment the amount of biomass getting into the water fountain varies (pollen, leafs, bird droppings). This supports the growth of algae.
Despite regular cleaning and chemical water treatment it can be very costly to keep the water fountain clean. Sometimes high-pressure cleaners are used. But for water fountains which are protected as a historic or artificial monument this is not possible. These measures can harm the surface and design.
