ok, so the shrimp was in there for 3 days before i removed it, the test results from that time was about the same as above. I then let cycle for 20hrs, and put a small damsel and four small hermit crabs in, to continue the cycle. now 24hrs hrs later i tested again, and the readings are showing 0 for ammonia, nitrite, and nitrate. also when i put the first and crabs in yesterday i over feed a little. not sure if the levels being at 0 is a good thing at this point? I think because i had the tank running with 15 lbs of LR
and 50lbs of live sand, that it had already begun the cycle before i added the additional 25 lbs of LR
. Thats why it didnt spike as much as i thought? does that make sense? any advise on whats next and how to know if there is enough bacteria in there?
