I kind of reluctantly post this, because in all honesty, I treat/acclimate all my wilds, the same way I do with my domestics. I use the "plop & drop" method for ALL my Discus. They are all dumped into clean, warm tapwater. No playing with water chemistry whatsoever...UNTIL I want to try and induce pairing/spawning activity. I never use bright lights with the wilds. Most times just indirect lighting. If I do have a direct light on them, I use floating plants. I also tint the water with a peat(blackwater)extract. I found wilds do seem to settle much easier when there is a thin layer of sand on the bottom. All wilds are different. There really can't be a specific timeline, since it's based on the actual FISH themselves. Some settle in right away, and movement and lighting around/in the tank is no longer an issue. I don't treat with meds unless the fish need them. Some treat right away. You're going to get a lot of different answers and procedures from a lot of members here. You'll have to break it all down, and see what works best for you, and your fish, as I did...Bill
