I am new to the group. I am currently setting up a 75 gallon salt water aquarium. I am in the process of cycling the tank. I have over 100 pounds of live rock with 60 pounds of live sand as my substrate along with 15 pounds of argonite. I have a marineland c360 canister filter. I just added two raw shrimp to my tank a couple of days ago. At least nothing on my marineland test kit color chart. I went to test for ammonia levels and it came back with nothing. I figured I would have some traces of ammonia since I just added the raw shrimp. Should I add more raw shrimp to the aquarium or should I go out an buy some pure ammonia. I was also wondering should I run the canister filter during the cycling process. Thanks
