If you look around the forum you will see a whole lot of happy people using chlorine and very few happy people using Baquacil. I have not used Baquacil so I can't tell you if it's good or bad but you have been using Baquacil and obviously you have not been happy. I am extremely confident that if you start up with chlorine your pool will be ready to go by Saturday and you will be a happy camper from now on.

Besides, whatever savings you might get from using up your old chemicals would be lost by the additional chlorine you would have to buy to convert later on. You could always try to sell the old chemicals on ebay.

Make sure you get a drops based test kit and if you have any problems on startup, post your test numbers and someone will help you out right away.

Good luck!
