Sorry....how I read what you "wrote" made it sound as if there was a new adapter piece to them.......Well with that said I do use the revs on some of my lines on my 8Way........3 work good, but 1 seems to be hanging up and not rotating like it should.....I've cleaned it several times and can't find anything hanging it up, but still doesn't rotate....All in all they are rather "neat", but they do hang down in the tank a bit....I think the picture on the site is a little deceiving IMO. Part of the skirt must be submerged underwater to get them to operate properly.......But if you can get over seeing them down in the tank a bit I think you'd like them.
