I already posted about this, but the post hasn't come through yet. We did this for my husband after 6 weeks of diarrhea after antibiotics with good success (it took almost a week after the FT for the stools to be completely back to normal.)We didn't use antibiotics, but as I said, he had already had antibiotics, that's what caused the problem. He was already cleaned out by the diarrhea, but you might want to do a regular enema first to get excess stool out. We used about a pint or maybe a cup and a half of distilled water with 1/2 teaspoon of sea salt to approximate normal saline. I mixed it with a plastic spoon and we discovered the hard way that you MUST filter the larger particles out or the openings in the tubing will get clogged. We also had it warmed up a little to try to get it close to body temp. We did it at bedtime so that he would be lying down for a long time after to let the fluid migrate as far a possible up the large intestine.
