Hello everyone,new to this site,but not to reefs.So, I'm starting a 40.I have about 30lbs of Argromax sand in with old used BLEACHED dry rock.Added water half way (to cover the rock) and have been running about two week.Added a washed raw frozen shrimp just over 10 days ago.So now,testing with strips,I'm not showing Nitrites or Nitrates.Kind of odd,as the shrimp is breaking down.My question is should I add another shrimp?I did add a sprig of sea grass to bring in some bacteria about a week ago.I only has ambient light n the tank during this cycle(?). I go slow on all of my start-ups as time can be your friend.Yes,I'll get better test kits later,just figured that these strips would work ok for the cycle.Any advice is welcomed. Thanks.
