Dry Rock

[tidal_waters]

OK, so I have had the 75 gallon with a 25 gallon sump up and running now for a month now and I'm hoping to get some assistance about cycling dry rock times.

I have 60lbs of dry rock in the main display with 60lbs of new sand. I have another 25lbs of rock from my solana in the sump. The pumps have been running for one months time. The skimmer has been running for 9 days, and last friday I had placed in a few Chromis.

I have been using Seachem Stabilizer in the tank for 9 days as well.

So far, I have yet to see any ammonia spike, and nitrates and nitrites are at a minimum. I was gone away for the first two weeks of the tank running. for the last two weeks i have noticed the following occurrences in my tank

1) a thin brown layer of algae film covered 85% of the tank
2) that died off and cleaned up
3) now I have little tuffs of green hair algae.

So for anyone else that had used dry rock in a new tank with new sand, how long did it take to cycle?
