The House of Hydro Mist Maker Kit (Mist Maker, Transformer, Float, 3 Replacement Discs)

what is the diameter of the floater? Will it fit inside a 4 inch PVC tube ?

Does this single Disc fogger come with the Tuff coating on it if so how do you know? Does it state it on the packaging some where?

Does this shoot a lot of water up? Had a no name one I was using and it shot water in a 12"-18" radius around the open container I used.

How can you make the fog denser? The fog is almost dry and I would like for it to condensate more on the surrounding area. Thanks
