take them back to the store and see if they will refund u the money if not get store credit or something. start with a new healthy batch from kenny and you will be addicted in no time i assure you lol.
30% bi weekly doesn't even come close to the amount of water changes needed for juvi Discus. The function of these large water changes is to remove most of the toxins left from their poop/uneaten food/food bits. The even low amounts of these toxins will stunt young Discus. This is why large water changes are done, to avoid that from happening. Before you start doing large daily water changes, I suggest you test the pH of the water in the tank and the pH of the water coming out of the tap. If they are the same, you're clear on doing large water changes. If they are a bit off, leave the water in a barrel with some air bubblers and allow it to sit for a day or two so the pH can correct itself. As for worrying about killing beneficial bacteria(bb) from the large water changes, that simply will not happen if the water is treated. I have done 100% water changes on my tanks before and I have NEVER experienced mini cycles. If your tank hasn't been up and running for a while, then adding Discus to the tank wasn't a good idea to begin with.
Also, the Discus pictures you posted up are of stunted Discus. Buying from LFS's are never a good idea unless you know what to look for. Try returning those Discus.. and read up on how to select healthy juvenile Discus.
sorry to jump in this thread but i just want to ask water something about what she said about the ph,, [I suggest you test the pH of the water in the tank and the pH of the water coming out of the tap.

How can you tell they are stunted? it does not matter to me if they are really... I think they are beautiful fish and if they don't grow an inch I'm fine with that. They look cool to me and are just something to watch swim around. the only reason I do WC is to remove nitrates.. I try to keep mine below 10ppm. I never have ammonia or nitrites in my tank. I do a water change and let it settle a little.. then check my nitrates.. if they are around 5ppm I do more water. I am not a noob to fish keeping.. I would not throw any fish in a new or uncycled tank LOL. I don't store water so doing such a large WC would be ludicrous for my tank. With my filtration toxins are not bad enough to ever need to change that much water off lol
