I guess I’m asking if the main tank would be considered as running fallow for 6 weeks if these little guys never show signs of Ick and nothing else is added. I also have 3 white-striped cleaner shrimp, 2 arrow crabs, 4 turbo snails, 4 blue legged hermit crabs and other small hitchhikers from the live rock. They are all in a 72 gallon bow front tank with about 40 pounds of live rock, 1/2 inch of crushed coral substrate, a remora skimmer, an Eheim professional 2 canister filter and 2 Maxijet 1200’s for water movement. Temperature fluctuates between about 80 – 82 degrees (the weather has been a little on the warm side here in Maryland and I can’t get it any lower than that unfortunately). Water is at 1.024, Ph is at 8.2, Ammonia is 0, Nitrite is at 0 and Nitrate is at 0 even after all the deaths. I do at least a 10 g
