Yea Sacc or Pink Powder?

I used Pink Powder for about a year and a half and it helped but he was still loose. I then tried BioPro by Feedmark and he has lovely shiny kidney pooh's :-) I now only wash his tail now and again rather than every other day, he was really bad. BioPro is about £1 a day but the do offers so can get it cheaper. It is yea sacc and something else (can't remember of the top of my head) but the do just yea sacc so could try that.
 
Yea Sacc - better value for money no binders/fillers/dubious ingredients!

Also why does the horse have diarrhoea? That needs addressing!
