For each frog, the recommended treatment is one bath for one hour a day. One teaspoon of Epsom salt per gallon of water in the bath (half a gallon = half a teaspoon and etc.)

More salt, longer or more frequent baths can shock your frog making it more ill.

You cannot rush their treatment now, just do them consistently and patiently and hope for the best. This thread began over 5 months ago and these frogs were already severely bloated in December...you may not be able to save them all but hopefully you can heal most and help them live healthier lives from here on out.
