This was and is my 1st tank. I started building and putting everything together in November about January I got the 180g tank set up With 2" of sand and a 100 pound of live rock. I had a 40 gallon sump put together use PVC pipe for plumbing, the water drained into a 3 stage filter system. 1st age was some foam pad for pre filter 2nd was either some Carbon or little circle things and the 3rd was bio balls. After there was the protein skimmer a bubble wall and I had 2 return pumps going back into the aquarium one on the left side one on the right side. started getting fish order in and yes the tank was cycled, ammonia and nitrates were all down to 0 and I used test fish to make sure it was safe. A couple of months later I had a good amount of fish in the aquarium. At that point I would say I had a good amount of fish I'd say 7 or 8 medium sized, like 3 to 4" and 4 little clown fish. At the time I did not have a quarantine tank set up. A couple of months into it fish started to die. The 1st to die was the clown fish. I thought it was ick so I treated for that, the fish still kept on dying and more research found out it was marine velvet by time I got this figured out almost Most all of the fish have died. All that I can remember still being alive was the blue hippo tank and like 6 mollys. So what I did was I douse the tank with copper for 3 to 4 weeks. I wanna say figured at that point things were good everything bad was an should have died. So I started to re introduce fish again I want to say back in March timeframe. Now to present day I think and believe I have marine velvet again. I do have a quarantine tank that I have utilized ever since the 1st incident. Almost all the fish have died now. I have been using ruby reef both the rally and ick to try and fix this problem. I don't have many fish left a blue hippo tang, lion fish, one Molly and for clown fish with a snowflake eel. The lion fish looks like he is not doing well and will be the next to die. I'm still using the medications tomorrow will be the last day for the rally. I am at the point where I'm done with it, not just because of all the money over $1500 I have spent on the fish but also its not fair for me to just keep getting them and killing them. I do not know what I'm doing wrong I watch my parameters done a lot of research, talk to my local live fish stores and I also have a Neptune system that helps out with watching parameters. I thought I would try one more thing and that is posting on here seeing what I have been doing wrong why the fish are dying and I don't think it's just because a disease some just seem to die but to early. The bottom line is unless I can come up with something or figure out what I'm doing wrong I'm going to pack everything up an sell it because that's not right to keep killing off the fish. Unless I get some great advice on fixing what I'm doing and know I would not do this all again. That is why I am here to ask the experts on their knowledge on this. But like I said if I don't know and I don't feel comfortable with starting it all again a I'm just going to sell at all.
Thank you all for your time and advice.
