This is my Osaka 320, an 84g curved glass, Fluval model with original stand, circa 2009. Dimensions are 47” x 17” x 25” high. It is the larger of my two Osaka aquariums documented in my journal: A Tale of Two Osakas

Filtration is 2 Oase Biomaster Thermal 850’s to spraybars. Lighting is 2 Current Satellite Plus Pros set to a medium/low output, there is cO2 hooked up via inline diffuser, which has been turned off for the past 9 months or so. Low light/weekly EI dosing with a 50% water change.
I set it up as this low tech planted, jungle style scape in 2022, but now I want to switch it up a bit and convert it to accommodate Discus (Symphysodon discus sp.). I have never kept Discus before, so this is an ongoing learning process for me.
I think this tank is a good candidate for the conversion - it is filled with anubias, java fern, crypts, and swords that will probably all tolerate the 82F I plan on keeping the fish. They are used to 76-77F already, and my plan is to gradually increase that a degree or two per week till I hit the target.
The substrate is thin -1.5” or so, and I am considering going barebottom, keeping the epiphytes on driftwood and pot up a few of the others.
I definitely need more swimming room, so step one will be to thin out the mass and remove a few plants and pieces of wood.
Step two will be to remove some of the incompatible fish - a few long finned danios, 4 glow light tetras (which I believe are modified black skirts) 2 Synodontis petricola catfish, and the dam*ed female albino bushynose that keeps having babies (I’ll keep the male).
There is also a combined school of black Venezuelan and gold lazer cories, which I will keep in the tank along with some black mollies which hopefully will acclimate to the slow temperature rise.
I will have to remove all of the driftwood to catch these fish, so if I decide to remove the substrate, I can get that all done at the same time.
I do want a fully planted look, so tomorrow I will start the thinning process and see what things look like from there … any advice from experienced planted discus tank keepers is more than welcome!
