Another way to go would be to find the largest diameter PVC pipe that will fit in the Jobo and cut a length of it, cap both ends and use it as a spacer that would hold the reel in place and obviate the need for so much solution.
The simplest option would be to buy a 2521 tank which are not expensive as you already have the reels. N.B. the 2523 tank has cog on lid and is for use on processor with lift. I don't think the lid on the 2523 is sealed so is probably not suitable for inversion. I could be wrong about that so perhaps someone with a 2523 could comment.
The reels you bought should each have two plastic pieces which clip into either side of reel after loading film. These put film under pressure in grooves. If those pieces are missing you are stuffed as film will come loose in processing. However it looked like I could see a couple in the photo.
