Right now pool water is very cold , it doesn’t require a lot of chlorine. But if you are not careful on regulating your pH chemistry by adding acid or using Tri Chlor tabs, you will find that the pool will calcify on the walls creating sharp crystals which could lead to requiring a drain & acid wash with possible sanding.  Here are some photos of what it looks like:

Calcium Buildup On Pools

I have seen this happen around our San Fernando Valley over & over again including a neighbor in Sylmar. This is an expense that can be avoided. There are several quick ways to check your pH; Test kits, meters and my favorite – dip sticks. Taking a few seconds can head off disaster.
