Hello Z-Lee,
Do you know if the replaceable 5.5ml glass on the Zenith Pro and Zenith II are the same thing? Healthcabin have both replaceable 5.5ml glass for the Z-II which are in stock, but are showing you need to pre-order the Z- pro glass. I just figured they were the same fit because they are the same tank with the exception the Z-II doesnt have the beauty ring the Z-Pro has? What do you think? Thanks!
I'm fairly positive that they are not. While I cannot find the specific dimensions for each glass, there are reviews online stating that they are not compatible and that was my original hunch. I would say to be sure, stick with a purchase that's specific for the Zenith II tank.
I would go with this link.
