I don't think its absolutely necessary to do it even once a week. Some of my frogs only go once a week. I feed them only nightcrawlers so then again by feeding them only nightcrawlers u shouldn't have a problem with them going. I think you should save the repta aid for a time when your frog stops eating all together and starts to lose weight.

If your saying that its coming thru the nostrils then to me it sounds like u make be using too much or doing this too often. Almost like your overdosing the frog. But maybe someone has another opinion.
