Proteus' Shallow reef build

[Proteus]

Picked up 30 lbs or so Marco rock. Put in 15g WC tank

My plan is to cycle the rock in that tank. When done ill tear down current tank put corals in bucket skid tank out move other one in place fill and put coral/clams in new tank. I am seeding new rock from sponges that were in current sump and started prodibio on it.

Does any one forsee a issue of a transfer like this. It should take 4/6 weeks to cycle rock.
Also do I need light on cycling rock

Also picked up glass for over flow box which was cut wrong size. Although it was cut too big so saves from buying more glass. I tried to cut it myself but I'm not that good with 3/8" glass.
