I just want to thank everyone here... I just left the local pool store after signing the contract for my 12x24 doughboy pool. While sitting there filling out paperwork I here a poor soul get talked into 30lbs of shock to get him through the rest of the season. He also left with various bottles of other ****. Ugh glad I'm not him. The salesmen sounded upset when I told him to keep all his start up chemicals and that I would maintain it myself. Got to love TFP.
