Most inground pools don't need liners - concrete/gunite and fiberglass pools have built-in surfaces. Only vinyl inground pools require liners, which need replacement every 8-12 years.
You can winterize a pool without draining by balancing water chemistry, lowering water level 4-6 inches below skimmers, blowing out plumbing lines, and adding winterizing chemicals. This method protects your pool structure and equipment while saving water.
Concrete pools do not need liners like vinyl pools, but they require a waterproof finish such as plaster, aggregate, or tile to prevent water loss and provide a smooth swimming surface.

Pool alkalinity typically rises due to fresh fill water with high alkalinity, adding pH increasers or certain sanitizers, excessive aeration from water features, and natural processes like algae growth.
Yes, your pool absolutely needs proper calcium hardness levels to prevent equipment damage and maintain water balance. Calcium hardness protects your pool surfaces and equipment from corrosion while preventing scale buildup.
