i set up a new system and used BRS reef saver dry rock. I got the tank wet on the 10th of this month, added a shrimp and dosed microbacter7 until gone. I saw my ammonia jump to .2 on like the 21st and has been there since. I have not seen any signs of nitrite. Just wondering how long it normally takes all I have ever used before has been live rock. Also tank is bare bottom.
