So a little of my story. I got the tank used for $2k plus I got three ai sols and a mp60 from the guy and gave him back the t5s for an additional $600. And he threw in a chiller. I got it up and running at the end of January. I did a fish cycle. Using three tangs. (Hippo, yellow, and lollipop). All went well. After about a month I added fish from a smaller tank I have (purple tang and borbonius) and a black tang from a friend who qted it for me. I had put a bunch of nice clowns in my qt and observed them for three weeks and they were super healthy. So all was going well. The tank came with a Magnus skimmer in place of the factory one. I purchased for fish from a lfs (Achilles, female flame wrasse, and a lineatus pair) and placed them in my qt and quickly watched them all begin to die off. Stupidly I also bought a bellus pair and a small blonde naso and put them in the qt. After I watched three of the four originals die I panicked and threw the female lineatus, bellus pair and naso in the display and boy did I pay dearly. The lineatus died that day and now my whole display has a nasty case of ich. All my fish are still alive a few are pretty banged up but alive and eating. So now I set up a 55 gallon hospital tank. I popped a few clowns in w live rock and special blend bacteria to jump the cycle. I'm going to put all my fish in there and treat w copper to cure the ich. I'm going to let the tank lay fallow for the 72 days to break the cycle. I weighed all my options and this is the only one that works for me (fingers crossed). While all this was going on I added three reactors (biopellets, gfo, and carbon) and a large media block to help w filtration because I have a black sand bed but a minimal amount of rock because I like the minimalist thing. I have some corals in there and at this past weekends swap grabbed a few more nice pieces. The crown is a beautiful bright orange acanthophelia that is quite large and eats like a champ. T
