I am currently running a FLUVAL fx5 on pure bio.
I do no use any kind of carbon, just pure bio.
this creates a HUGE bacteria base to keep the chems in check.
all my chems are 0 across the board.
I do a water change once a week, but that's about all.
the tank takes care of itself.
it's all in the filter and your stock.
my cats clean up the bottom and my bio filter takes care of the chems.
the pool filter sand is very dense and no particles can penetrate it. simple hover with the syphon for 5 seconds and all is clean.
ALSO, I do not stack against the back wall, I have a front channel and a back channel for the fish to swim, this creates great water flow and it flows right into the intake.
here is behind the scene, you can see my FX5.
also have a UV
light on the return.
I have extra fx5's just in case.
I also have everything on battery backup!!!!!!
