My FC is a 1. Checked the bac pac and it was empty and I don't have a refil on hand. Is it safe to use bleach when I've been using Trichlor tabs? And can I go back to using Trichlor tabs after adding bleach? I know it's all chlorine, but still learning and not sure how it all works.
Oh, BTW, the bleach on hand is GV. The active ingredient is Sodium Hypochlorite 8.25%, Other ingredients 91.75%. Yields 7.86% available chlorine. When using the pool calculator do I use 8.25% or 7.86%?
