Anyone use beneficials in their medium?

I think your making people paranoid...It takes less then 24 hours for the clorine in my water to evaporate.
Get a clorine slash PH tester for pools.Thats how I test my water after I let it sit out for a day.

In my area they switched to some new form of chlorine that lasts longer to eradicate e-coli...
My goal isn't to make people paranoid..just to make them aware...
I used a whole 500 gram bottle of piranha over the past few months without thinking about this little detail...
