Shocking the pool will lower the pH, whether you use chlorine-based shock (calcium hypochlorite), or the non-chlorine kind (potassium peroxymonosulfate).

Why is there algae on the bottom of my pool after shocking?

Pools can immediately turn green after shocking when they have metals like copper in the water. These metals oxidise when exposed to high levels of chlorine which makes the pool water turn green. Adding a metal control product such as Zodiac Metal Remover will help to restore the pool water.
