I new and not sure if im on track or not. My tank has been setup for just under a month, started with base rock, sand, heater and couple power heads. I have a upgraded power head coming in tomorrow. its gonna be a sump less system for now, since i have no room for one. Will be ordering a skimmer here in a couple weeks. The tank is gonna be a FOWLR. 2 weeks ago i bought a live rock to help get the cycle going. This is the part im not sure on. The LFS said it was really good rock and people been having good luck with it and the tank should cycle pretty quick. Well since i put it in the tank my Ammonia has been .5 and everything else is at 0 for the last week. Sunday i asked the guy at the LFS thinks im getting a false positive on the ammonia and that tank may have been cycled already since everything is at 0. For the last week my base rock is getting Brown looks like brown felt. and now the sand is getting a hint of brown. i was told this was gonna happen which is a good sign i guess. So could of my tank cycled already or is about too. im in no hurry for fish, just want to make sure whats going on with the tank.
