good day,

im building a 25 gallon cube reef tank with a sump- my first sump. my end goal is to have a perfect reef 0 nitrate and 0 phosphate(most important) but still want to keep "slightly dirty" water

what do you all suggest in putting in the sump

miracle mud?
4-7" DSB
4" dsb with 20 lbs of live rock
Bare bottom with macro
bare bottom with just live rock
carbon in the filter sock,
gfo in the sock


what do you suggest?

i plan on keeping mainly LPS with some SPS
