Hello Folks,
I have one of those hand held digital testing units that uses a dip strip to test water. It works great for Alk and PH but the CL always comes up 0. Can this thing accuratly check Chlorine or am I flogging my dolphin with checking it on it?
My other question is dry acid, do you really have to add it to a seperate bucket of water and wait hours to dump into the tub or can you just broadcast it into the tub in small amounts?
Thanks for your advice,
