Why is the live rock in the sump and not in the display tank? What do you have in the tank for decoration? Sand? Did you wash the sand? What is this 3-day cycle? Sounds like a gimmick product. Do you mean the skimmer water is brownish green...or the water in the sump? The sump water should be the same color as the display tank since it is all running together.
