8 oz Jack's Magic Filter Chlorine Reducer

Jack's Magic - After Shock - 8oz. Container

After Shock chlorine reducer does exactly what the name implies... reduces chlorine levels! After Shock is a must for commercial pool operators that need to quickly lower the chlorine levels in the pool shortly after shocking. After Shock will normally lower chlorine levels in about 30 minutes... much better than waiting several days for it to burn off in the sun!

A little bit of After Shock goes a LONG way! An 8oz. jar of After Shock will lower the chlorine level 4 ppm (parts per million) in 15,000 gallons of water! It’s important NOT to overdose with this product... it will actually stay in the water until it has chlorine to neutralize, which means it could be very difficult to reestablish a chlorine residual if you overdose!

In most cases, After Shock should be used with Stain Solution #1 for stain removal purposes. A high chlorine level can actually neutralize the Stain Solution #1, but After Shock can bring that level down quickly and easily, preventing a long wait before treatment.
