the tang and damsels are gone. I was able to give the tang away and everyone told me the damsels were a nightmare so I took them to the LFS. The 36 was initially my only tank but I couldn't resist upgrading to a 75. I've started my cycle on the 75 so hopefully will be finished in 4-6 weeks and ready for fish. When I started the 36, i bought the live rock from a LFS and it had been in thier tank for a long time. Someone on here told me I wouldn't have much of a cycle since the live rock wasn't out of water but for about 45 minutes and then put in my tank. The amonia level went to .5 and then went back down before I added anything. Was that a good enough cycle? My thoughts were since the 36 was already cycled, I could turn that into my QT and then use the 75 as my display. What can I do to make the 36 ready to be a QT and once that is completed, would it then hold those fish until my 75 is cycled? Are those the wrong type of fish for me to put in the 75 after it cycles? I did order the live rock for the 75 online so its going to most likely really cycle, unlike the smaller. I really am just surfing my options on my fish, not necessarily ordering right away, just bored and thinking what I could do. One more thing, the 75 has a sump wet/dry for a 90 gallon tank, a protien skimmer, and a doulbe HOB filter. Is this sufficient? Your thoughts on where I should go from here would be greatly appreciated.
