The rough buildup on your pool walls are most likely calcium carbonate. Similar to stalactites and stalagmites in caves build in or on pool surfaces because there is a lack of chemical balance in the water. Your pH is running constantly at or above 8.0 pH. The only way to remove them now is to drain and acid wash and/or sand the pool surface. You are likely, too, to not be able to remove them completely but you will be able to control them with vigilant monitoring of your water chemistry. k
The purpose of the plaster scratch coat is to provide a rough surface for the next coat of plaster to adhere to, ensuring better adhesion and a stronger bond between the plaster and the surface being covered.
The purpose of applying a scratch coat plaster in the process of plastering a wall is to create a rough surface that helps the next layer of plaster adhere better. This base coat also helps to level out any imperfections in the wall and provides a strong foundation for the final finish coat of plaster.

Aggressive water chemistry and age.

Materials that have microscopic irregularities or rough surfaces tend to scatter light more effectively. Examples include frosted glass, white paper, and rough or textured surfaces like plaster. These materials cause light to bounce off in various directions, leading to scattering.
A coarse plaster of lime, shells, and pebbles used for outside wall surfaces. A rough preliminary model or form.

The primary difference between plaster and fiberglass pools lies in their surface materials. Fiberglass pools have a smooth, non-porous surface that resists algae growth and remains comfortable to the touch, while plaster surfaces can become rough over time and require more maintenance. Additionally, fiberglass pools are less prone to chipping and cracking compared to plaster pools, making them a more durable choice. If you're interested in exploring high-quality fiberglass pool options, be sure to visit Pools-Now.
Because it is studded with ribosomes that cause it to be rough.
It might be a scratch you gotten a long time ago and you don't remember it.
Rock lath plaster offers several advantages over other types of plaster for wall construction. It is more durable and resistant to cracking, providing a longer-lasting finish. Additionally, rock lath plaster is fire-resistant and can help improve sound insulation in a building. Its rough texture also provides a good surface for paint or wallpaper to adhere to.
