Greetings I’m setting up a 75 gallon discus tank and wanted to get some opinions before I commit to a substrate. I’ve got an RO/DI system ready, I’ll be running a Fluval FX4 with a spray bar, and lighting will be two Hiro WRGB pendants. The plan is to stock 5–7 discus (either juveniles or around 5 adults) along with a school of about 15–20 Rummy nose tetra. I’m aiming for a clean, minimal planted tank with jungle val in the background and maybe a tiger lotus or an oriental sword as a focal plant, along with some lava rock and manzanita. In the past Ive done gravel and dirted tanks, and I was originally leaning toward doing a dirted setup again using an organic topsoil capped with sand, but I’m concerned about long term stability, especially with discus..mainly the cap getting disturbed, nutrients leaching into the water column and how that might affect water quality. I’ve also considered something like sratum, but I don’t love the look of it. For those of you who have run planted discus tanks long term, would you go dirted, stick with sand and root tabs, or recommend something else? I’d really appreciate your thoughts. Thanks!
