I've read that not enough chlorine when shocking can be bad. Can too much be a problem? I purchased "hth" brand Liquid Chlorinator at Wal Mart - package says 10% sodium hypochlorate. I think my pool is about 12000 gallons.

Package instructions say 58 to 116 ounces per 10,000 gallons. If I used a full gallon would that be too much?

Thank you.
