Tank is nearing 2 weeks, water still looks good, still zero for ammonia, nitrite and nitrate, pH is at 8.3.....only think I notice is that some rocks are starting to turn a little green...which is a good sign i guess...my AquaC remora HOB skimmer pulls about 2 gals. of water everyday...i hope this is due to break in period. had the collection cup set to the highest..
