You CAN do this yourself, it is very simple. You need a good drops based kit. We are all partial to Ben's kit he sells here as it is hands down the best. You can run to Wal-Mart and pick one up until you can get Ben's kit. You need to see the above post, and add enough bleach to get your FC to 15. Do this 3x a day, and when it holds a reading of 15 overnight, you are done. I did this and it took me 4 days. My pool is simply amazing now. After you finish, you will sava a lot of time, $$$, and headaches by using the BBB methods as told here on this site. Go buy a lot of unscented ultra bleach, most use the Wal-Mart generic stuff, and a drops based kit, and get to work! I assure you, it is a lot easier than you think, and the folks here are great and will help you with any issues you may have. Good luck!
