Hi I re-set up my 90 gallon tank a few weeks ago I used play sand from my home depot and cleaned it very well after a few days the tank cleared and then my live rock arrived it has bben in my tank for 10 days now I have added stress zyme to start the bilogical system and I am beginning to notice my live rock is turning brown and I do not know if that is natural or something is wrong the ammonia has cycled but the nitrites are high. any suggestions or if this is all part of the cycling procees please let me know

If it looks like brown film, it is diatom algae. It appears in all new tanks and will disappear when all the silicates that are in your tank are used up. Then you will get some hair algae and cyano bacteria blooms which are realy fun. This is all normal as your tank matures. If your live rock turns purple that is good as that is corallline algae.
