Marine pure block? DSB? Placement?

[nanomania]

Hey guys, iv read that 1 marine pure block is ok for a 100g, i would like to know its placement, does it work exactly like a dsb? Im sure if water passes through it, can cause no3 issues as debris can get collected over time. Is it really worth? Howmany bio pure blocks for a 150g? Does it mean i can add less live rock? Im asking coz i prefer less live rocks and more space for fishes to move around.

1 of the blocks equals 23,000 square feet of new surface are. I run one in my sump with about 20 lbs of live rock/rubble for a 72 gallon DT with only 40 lbs of rock in the display. Oh and I use the marine pure balls also.

I use two 8x8x4's in my 280 only got about 120 lbs live rock.
Note it will keep nutrients very low I did have to cut down water changes to keep measurable nitrate and phosphate which also will lead to more dosing since wc may not replenish alk and Calc fast enough

Sorry meant 180 not 280

Do you let water pass through it or use it like a dsb? Can u post a few pics of your placement? What other medias do u run?
