has any body usesd this system

[Ruth]

I do not use that particular fuge however I do use the ecosystem miracle mud in my sump/fuge and am very happy with it. My tank is only 8 month old however so probably need more time to tell. I was convinced to use this system based on a friends tank that has been using this for probably 6 or more years and flourishes. You can also go to fragexchange.com and see SueT's tanks - she has been using this system for a few years as well.
