I'm sorry, i was typing when you left this post, so I missed osme of this information... sorry!
bottled water is not guaranteed to not have chlorine, chloramines in it. You still need to use the water conditioner. It's cheeper to use a water conditioner, de-chlorinatoer and tap water than it is to buy bottled water. And it's better for her.
It's good your not using distelled. But now that I know you were, that is another cause of MBD, it was draining all of her minerels in her body. By the way, the distilled water isn't good for fish either.
I would stay away from the phoenix worms for now, and use the reptiboost to dust small crickets only if you need to force feed. Or even if she's free feeding. Als use calcium every day for now and multi-vitamin once per week. I think she's severely malnourished and needs extra calcium. Phoenix worms are hard to digest, I hear. And if she's not well, that could cause a whole other slew of problems.
A repti-boost bath is a good idea.
Use pedialyte solution (1 part to 10 parts water) and add one of the little scoops full of repti-boost. Use treated water for the bath, and make sure it's fairly warm and not too deep. Soak her about 10 mins, then soak her in a warm clean treated water bath to rinse her. This could give her the nutrients she needs to begin eating on her own again.
