Hi, and welcome to TFP!
Most of the baqua users you find here are FORMER baqua users. Many people can maintain a baqua pool for a few or even several seasons without any problems, but eventually there are problems, pink mold, white mold, other slimy things, and perpetually cloudy water... which require the addition of stronger and more expensive baqua chemicals. The baqua chemicals are not cheap, and they are also not approved as a sanitizer in other places (Australia comes to mind...)
Save yourself the trouble of converting later, and start with chlorine from the beginning! If you read through Pool School, you will see how we use inexpensive products, and knowledge of your pool chemistry to properly maintain a sparkling, sanitary pool. That's BBB in a nutshel!
