I started SLAMing my pool tonight and followed the instructions to look up what FC (16) to get my pool to for shock level, given my CYA level (35). The pool had basically no chlorine in it after a weekend of swimming, so PoolMath said I needed 4 gallons. Except I didn't realize it was set for 6% bottles when the ones I had were 10.5%, so I put in about double what I need and have the pool at 40ppm right now. Should I be worried or do anything about it? I'm not guessing there's much to do.
