#ed_op#DIV#ed_cl#I am sure the articles are the same ones I read. I actually read one when it was published years ago. I have been following reef tanks for a whilie; I think I am ready to step off into it (fingers crossed).#ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl##ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl#I agree that a closed system is a very poor scaled model of the ocean environment. Hence all the mechanical devices needed to support the biological density most everybody wants in a tank. I do like the idea of a "bare bones" system with as few mechanical devices to fail as possible.#ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl##ed_op#/DIV#ed_cl##ed_op#DIV#ed_cl#I hope this gets around, and somebody that may be running this system chimes in on their experience.#ed_op#/DIV#ed_cl#
