Have you added TRUE LS
to your tank.. What are you using for a substrate.. Copepods like sugar size sand.. Also it depends on where you got the LS
if any from.. They would not get into the tank unless introduced somehow.. My tank is less than 2 month old and they are everywhere.. I added 15lbs of LS
It was full of all sorts of critters.. If you want to pick up your population of copepods rather nicely I would say to add 10+lbs of good LS
to your tank.. Stay away from the stuff that comes "prepackaged" The more the better... As well as all the usual 0 ammonia, 0 nitrites, less than 10 nitrates, Salinity 1.025, temp 80-82... If I am incorrect someone please correct me..
