LOL, sometimes less is more.
I quit using any filler in my carts and just drip, But I also do not use any automatic batteries either.
I haven't even looked at this stuff, but at first thought just going by the brief description, makes me think it is of the stuff that is used in some of the higher end AC filters. If so, I have a bunch of it, and one side of it is blue, the other side is white.
I wonder, if it is blue in color, if there is something to be concerned about with the dye that was used. And if a dye was used to make this stuff blue, will it leach out into your liquid? Also something to be considered, is this stuff made of flame retardant materials? If so what chemicals if any were used to make it flame retardant.
