We set up our salt water tank tonight with a combo of dry / wet (live) rock, sand, and salt water. Everything is good to go, but we have no ammonia source. We thought there was frozen shrimp in the freezer, but were mistaken and now stores are closed. We are afraid of messing up the cycle we just started... any advice? We do have frozen tuna and frozen shrimp (that is mixed with sauce).. should we rinse off the sauce and just throw it in?
