You're right, when it comes down to it it is just advice, and some people on forums are wrong. However I've kept frogs a lot longer than you, and the others chiming in have kept frogs longer than me. We are not giving you this advice off of "I feel like I should tell her to do this today...". It's from years of experience and trial and error.

You can do as you'd like, but expect problems such as impaction, water retention, and toxing out syndrome, to name a few.
