so, a little backstory. I bought a used 75gal tank that had some soft corals, three fish and some snails, crabs etc. I moved the tank and had everything set back up within 48 hours. I saved as much water as I could, and used the rock. I figured the tank would still go threw a cycle. I have had it up and running for three weeks now, and only had my ammonia go up to .25 for one test. My nitrates and nitrites have not moved at all. I’m running a filter sock and didn’t realize they had to be changed out as often as they do, and it was two weeks before I changed it and kinna figured that might have been the reason for the slight ammonia spike. So my question is, is the tank cycled?
