If the water level in your above-ground hot tub is dropping, it may be due to evaporation, leaks, or excessive splashing. Check for any visible leaks around the tub, fittings, or Plumbing connections. Additionally, ensure that the water is not being splashed out during use or due to high water levels. Regularly monitoring and maintaining the water level is important for optimal hot tub performance.
Rime frost is freezing water vapor that condenses at ground level.

So that the water doesn't drain out of the pool and so the pool doesn't fall over. I agree with the answer above but I have a more detailed answer. In a round above ground pool the water puts even pressure on the pool walls, and if the ground is not level one side will get more pressure. The imbalance will cause the pool to collapse under the strain.
When water vapor in the atmosphere freezes at ground level, it forms frost. Frost is a thin layer of ice that develops on surfaces like grass, cars, and windows when the temperature drops below freezing.
A depression in the ground caused by the removal of groundwater, resulting in sinking land surface levels.

In simplest terms, an above ground pool pump is a flooded suction pump, which means the water level must be higher than the pump for it to operate, and an inground pump has the ability to draw water up from a level lower than the pump. The engineering and structure of these two different types of pumps is what makes them work the way they do. This means that, in a typical installation, you could use an inground-specific pump on an above ground pool, but not an above ground pump on an inground pool with the water level below the pump.
After a flood, the water level drops as water recedes or evaporates. This process occurs as the excess water drains away through rivers and streams or soaks into the ground. The decrease in water level is a natural response to the balancing of water supply and demand.
Above ground pool pumps are made to sit at or below the water level, not to pull water up. If placed above the water level, or away from the pool-side they will not circulate the water properly and may not even prime. For your well, a better option is to go for an in-ground pool pump - or better still, purchase a pump made for your particular application.
For every thousand (1000) feet above sea level, the boiling point of water drops by two (2) degrees. Water at sea level boils at 212 degrees Fahrenheit or 100 degrees celsius. Fifteen (15) feet above sea level will make no real difference to the temp needed for boiling.
