So my 75 gallon tank w/ 55 gallon sump is up and running with salt. No sand yet, but there is roughly 70 lbs (three pieces) of dead base rock in the tank and maybe 30 pounds of dead rock in the sump, along with a 7"x7"x4" container of ceramic noodles. I placed one ten pound piece of live rock at the "upstream" end of the sump, sitting on another piece of dead rock. The tank is currently unlit, the return pump is an eheim 3000+, and I have an SRO-1000 skimmer. For circulation in the main tank I have one Koralia 1050 (will be adding a second), there is no additional circulation in the sump yet.
So my question: how fast will bacteria spread from the live rock to the dead rock in the sump, and will it spread faster or slower to the rock in the display tank? Given that I have 10 pounds of seasoned live rock (came out of a refugium that has been up for a year), can I safely add a damsel to the tank in 10 days or so to help the cycle along?
