That was a nice tank, Yvette!
I had a 55 gallon with stand and an Eheim filter that I gave away one of the last times I moved. I wish I had it now!
Have you considered using BioSpira instead of fish for cycling? That's what I did with most of my tanks. Now, I use seeded media from my larger tank if I need to set up a new one. You may experience very slight readings for a few days with the BioSpira, but it's basically an instant cycle and you can add the fish immediately, although I wouldn't get them all at once because the nitrifying bacteria won't be established well enough to deal with all the ammonia, etc.
I hope it's ok to post the link to FnF, mods.
Here's a pic of one of the dividers I made for a 6 gal Eclipse. I used cross stitch plastic, which is less than $.40 per sheet. I happened to have some plastic from another tank divider, so I used that for the top, bottom and sides, but others have used the binders that you find on files. You can also use suction cups. I'm quite sure there's a how-to thread on FnF with pics of that.
Here's the divider in the tank before the fish and decorations.
