I think I've gotten to the bottom of the itchy carpet removal.
It's not the carpet. I ripped out and carried the last of it to my truck last night. No itching.
However, when I started cutting into and removing the backing pad (under layment) Is when I started to get itchy arms. On closer inspection, the part that faces the cement floor is fiberglass matting. When I cut into it, I released fiber glass particles that cause the itching. I had been yanking up and rolling up strips of carpet and backing all at once two days ago. But yesterday I removed the carpet first and the the backing later in the day. And started itching then.
I'm starting to lay flooring this afternoon after work. There is still the issue of the giant aquarium that I haven't resolved yet. How to get it back into position without marring up the new floor. It's on a few dollies. The dollies will crease the flooring if I roll it and it can't be lifted unless I can find two other big men to help. My brother and I got it up on the dollies with leverage bars. Now it's sitting near the kitchen in the area I plan to floor last. It must be "manhandled" and carried about 25 feet.
It isn't like building the pyramids, but it will take some engineering. Possibly requiring the dismantling of the thing and then re assembly.
i have no doubt you will come up with an ingenious solution
