Thanks , no , it is suspended in the water itself , this appears to be on the surface . Also it isn't that red , it's more of a rust color . It seems to be about 6" below the surface and goes down out of sight . It lays in long feathery rows much like fog would . If you put dye in the water and took your hand and swept past it , it would look about like this stuff . I put some under a scope and they appeared to be little round , rough globs , like little barrels ???
