i have a pool heater pump installed with my pool pump for an above ground pool. My question is, Is it ok to shock the pool with a heater pump on ? because the heater and the pump has only one switch.
Yes, you want the water circulating when you add shock. Just try to avoid a concentrated dose going into the skimmer (and therefore into the pump/heater). Add your shock chemcial away from the intake to avoid this.
