Midwest HearthNatural Decorative Gray Bean Pebbles 1/5" Size (2-lb Bag)

Q: Can i sprinkle this on wet concrete flooring paint for decorative look?

I'm not someone who would know how to do what you've asked, but it would be beautiful if you can sprinkle them in the concrete and embed them enough that the floor feels relatively smooth. It would be an unusual and gorgeous floor treatment!

Q: Will these work as paver filler? Used Vigoro white pea pebbles last spring. Now the other half wants grey.

It could but you don’t get a lot in the bag better off ordering some from walmart

Q: How many pounds would be needed for a 8 gallon tank?

I would say a few bags of them would do I thought that they were a larger quantity for a project I was going to do but when I realized how much it was I haven't used themcyet

Q: can you use these in an aquarium?

Well it says it's all natural stone, no fillers, stains, oils, ect. So I don't see why you couldn't use it in an aquarium. It would have been kind of nice if OA had given more than a one word answer to how they determined the answer was no. Maybe they have more information.
