Recently finished building the stand and plumbing the sump to the 125 gal tank. It's been a long process but feels good to be finished. I moved the 4 discus from the 75 gal tank that contained a gravel substrate with plants and drift wood. After lots of research I decided to try bare bottom with potted plants. I have the drift wood soaking in another tank. Once it's water logged I plan on placing it in the middle. The final step will be adding 6-8 more discus with community fish in July.
