Free to good home.

I’ve been swapping out my marine pure balls for rubble in my sump. Have some that are out and dried, and more to be removed (plenty of good bacteria )

let me know
 
For nitrates you need the marine pure blocks. The 8x8x4s. Reason is you need anaerobic bacteria the grows in oxygen deprived regions to break down nitrates.

The balls can help some but won't do much unless you have a lot but even then that's questionable. Chaeto or soft corals will be better at sucking up nitrates. Pulsing xenias, or kenya trees... fast growing types like those
