Im still new to tfp however, i will soon be a supporter i was curious if i should bring my chlorine level to shock after its rain for a couple of days? i do know keeping my pool balanced it prevents me from having issues but i was gonna drain it to the correct level and then bring fc chlorine up alittle. im using 10% bleach and have realized that minutes later after adding my ppm goes exactly where i want it but i would rather be safe then sorry no room for the green monster
