so my question is , is my current low test result for CL level accurate or is it false possibly due to the Yellow out...in other words is the Yellow Out consuming the bleach I add , or is there really alot of hidden CL in my pool when I read 1-2PPM? thanks 4 the help guys & if I remember correctly Bromine is the main ingriedient , I put in the proper amount for 20k gallons > 2 bags

also, is it necessary to clean out the Bromine pool w/ bleach , or does it just return to normal soon?
thanks
