1. A modular filtration assembly for a fish tank, comprising:
A first module having a front and a slotted back in spaced apart relationship defining a filter chamber, the front and back of the module defined by a perimeter;
wherein the slotted back is further comprised of a plurality of slots sized and shaped to allow water to flow into the front opening and exit the slotted back;
a front coupler affixed to the front and a back coupler affixed to the back of the first module;
a front opening formed into the front of the first module; and
a buffer module having a buffer front and a buffer back, the buffer back formed with a pipe coupler;
wherein the back coupler couples to the front coupler when the back of the first module is positioned immediately adjacent the buffer front;
wherein the filter chamber is adapted to receive a quantity of filter material selected from the group of filter materials consisting of chemical, biological, and mechanical materials and materials combining two or more mechanical, biological and chemical filtering functions through the front opening;
wherein coupling the first module to the buffer module has a predetermined coupling strength insufficient to withstand water pushed through the first module and buffer by a pump; and
wherein the predetermined coupling strength is sufficient to maintain the coupling of the first module to the buffer module when water is pulled through the first module and the buffer by the pump.
