How to Use the Shock Calculator

Enter your pool volume to calculate the required shock dose to super-chlorinate your pool to 10 ppm free chlorine. Shock treatment breaks chloramines and kills resistant algae.

Always shock in the evening or at night. Daytime sunlight rapidly degrades unprotected chlorine (shock does not contain CYA stabilizer).

Wait until free chlorine drops back to 1-4 ppm before allowing swimmers to enter (typically 8-24 hours). Pre-dissolve shock in a bucket of water before adding.
