have you heard of this equip??
 

Greetings,
I am interested in getting involved with the ecosystemaquarium system.
It would be large enough model #3612 or for up to a 120 gal. Does anyone have any experience with this set-up? or any ecosystem products?

Thanks
Dwight

im not sure of the model numbers but i have an eco systems 30 gallon setup with 20lbs of mud. works great and more than supports my 90 without a skimmer.
