Thanks for all of the help and input so far. I am sorry to be a pest but like everyone else on this great site I am a little nervous. Can I use any kind of bleach and will chlorine work in its place?? Also how many gallons at 1 time should I be adding to this ?? Not total I know but do I want to try 5 gallons at a time. Thanks. I am not afraid of the strange colors you should see what color the Baq has it at now which is my last straw after only a year and why I am finally ready to convert. Thanks again for any and all guidance.
