Put the carbon pads in if euthanasia is your goal. I don't think it is, somehow. They are useless anyway - just a marketing thing to keep you replacing them. I haven't used carbon except to remove meds for decades. Velvet kills. Always remember that. It has a serious head start in your tank, and is very dangerous right now.
Plants won't be happy, but should survive a week. You could try 5 days, have a look and be careful.
Do the water change, redose, and do a water change a few days later. It usually takes about 2-3 weeks to beat it completely, though the last time I saw it here I killed it in a week, with no return. The only thing you could have done to help velvet attack would be if you haven't been doing 30% every week. It's a dirty water parasite, and no, dirty water doesn't show on test kits. Overfeeding, not changing water regularly - that's how things like this take off (and what may have happened before they even hit the store). Here, it's when I overfeed young fish.
The tank must be dark. No ambient light. The creature feeds on light.
