The problem with those product reps is that they can tell you what their products are supposed to do but have very little practical experience with using them. Same thing with vets. You see comments all the time about someones vet says this or that about husbandry practices when they have limited practical experience outside the lab. Not ragging on vets here. lol The methods in those stickied care threads are tried and true methods based on years of real world experience.
