1. ABSOLUTELY NOT CORRECT Epson salt works by a chemical reaction that is fairly harsh and veeeery dehydrating. It kinda works on the principle that the body reacts to it as a poison. It's OK once in a while but definetly NOT something one does with regularity and DEFINITELY NOT when one is on a limited nutrient regimen like fasting. The SWF is composed of 2 tsp of uniodized sea salt in 1 qt of warm water and it's a gentle flush that passes through the system and cleans the whole GI tract top to bottom. It works on the principle that this salt to water ratio is the same specific gravity as blood thus the system does not absorb it .
2.NEITHER is part of the MC and not in any way shape or form related to how the SWF described above works.
3. The book gives you SPECIFIC tbsl and OZ measures. Read it again or go to the FAQS on this forum for a bulk recipe.
Read the book. It has all the specific information that you need to do the MC proper and get the best results. The combination of the lax tea at night and SWF in the morning is all you need during the MC. I would wait to do a colonic after finishing the MC as a mop up operation. Some folk do colon cleanses with Oxy Powder or some of the other oxygen based protocols after the MC.
