Did you happen to test your ammonia prior to adding it or Dr. Tim's? Just wondering because I am using dry Pukani which I pressure washed, then leave in a tub of bleach, water change, bleach, water change, phosphate / lanthanum chloride bath, water change, more lanthanum cloride bath, then pressure wash, and in the tank for scape, sand, and fill with ri/ro water. My initial test is reading between 0.4 and 0.8 of ammonia.
I thought Dr. Tim's all in one required an ammonia base of 2.0 before you add the all in one product. Figured I'd ask before I add more. I'm guessing some of this is from the dry rock still assuming I didn't get it completely off. I have not added anything but the ri/ro water with instant ocean sea salt. SG is a bit high for some reason about 1.028 which I was shooting for 1.027 which is what I run my current tank at. I will be adding a bit more ri/ro water to the sump anyway so it may balance out.
