For those of you who have tried both Mazuri and FRM. Which did you have better success with? Also, which version of FRM did you use, 15 or 25?

All I've ever used is FRM. I don't think it comes in 15 or 25 , that must be Mazzuri.

FRM does not advertise the 15. When I asked them about it, the lady from FRM claimed they didn't make a 15%. However, when I told her I have a bag sitting in my garage she did more research. It's special order. The product they advertise is the 25%. http://www.frmfeeds.com/80712/74012.html

The 15% is not on their website.

I use mazuri in a multitude of ways. I can't say i have tried FRM will be checking out though.
