Have been reviewing the info here and have decided to take the plunge to the BBB method from Baquacil. Wish me luck! I've read the conversion process posts and other related posts but I'll probably need some help from one of the forum experts down the road. Just ordered the TF-100XL and plan to stock up on bleach to begin next weekend.[attachment=0:awefysjo]DSCN0524x.JPG[/attachment:awefysjo]
