On the weekend I did a parameters check with an API 5in1 strip and, since I trust old school stuff, I also checked it with the test tubes. The results where trites=0,trates=0, Ammo=0,PH=8.0,SG=1.022-1.023, the sand bed has been getting brown and air bubbles have developed in it. I don't remember mentioning to you guys that I had bought 5lbs of live rock to seed the rest...,but I did. I also bought two blue damsels. Not all of my rock is covered in brown only the sand and live rock. It has been a week and my levels read the end of the cycle. I don't know if it is just too early to be reading anything? Should I put in a CUC or not yet? I also added more dry rock about 20lbs on the 4th day.
