Newby and Sharon,

Do everything in your power to stay away from baquicil. You can easily use chlorine and can use any chlorine tab that will fit in the chlorinator. (tabs have some other issues but disregard that for now)

I suggest that you read the sticky posted by CarlD posted near the top of the forum in which you posted. That'll lead to more questions but we will be glad to help you with the answers. Read everything you can on the whole forum...especially the stickys....and ask questions.
