Sanitizer is the only chemical that runs continuously. Everything else exists because sanitizer alone cannot hold a pool: shock deals with what the chlorine cannot burn off, balancers keep the chlorine effective, and the protect step, algaecide, phosphate control, enzyme and clarifier, makes the pool a hard place for algae to start and clears what is left in suspension.\u003c\/p\u003e\u003cp\u003eTwo shocks, on purpose. Non-Chlorine Shock is the weekly oxidizer for a pool that gets used: no chlorine added, no stabilizer added, swim again in 15 minutes. Di-Chlor is chlorine shock that dissolves fast and will not bleach a liner, for the week the water needs chlorine as well as oxygen, and it is the shock for vinyl and above-ground pools.
