Should be ok in either, I know folks who have set them up in the 3.5ml tanks, the 6ml should definitely work.
Thank you. As far as the "figuring out" goes regarding balancing pressure etc., that doesn't really trouble me. I was just wondering if there was some inherent problem with a cheapie basic tank that could not be overcome. If it matters, the larger carto tanks I have have the flat delrin caps. If it works I'll put up a pic, just to shock everyone. lol
I really, only, like the flavor I get out of attys versus cartos Vivi setups etc. so this could be my nerdvana.
I really do like the look of that GV telescopic tank but... one pricey step at a time.
