Thanks Fred, I actually did see that post prior to posting my question, and it does help a little, however everyone is talking about regular 10 gallon visibles in that thread.
Gjones mentions his tall 10 on his response, but it doesn’t say what manufacturer of tall 10 (I assume it’s a Wayne). He also didn’t mention the size of the globe he has on it. He just mentions the space left to his 13’ ceiling.
Much appreciated either way though, thanks for the lead. I need all the help I can get.
If the cylinder is the only real difference, I can figure it out with the 37” cylinder size in jacks book, I just need to make sure the lower half (skins, base, jar, etc) are all the same as on a regular 515.
