After 24 hours of letting it set under the light (left it on overnight) the foam expanded almost to the top of the tank. I'm on vacation this week but now I'll be able to get back and finish up. I'll scrape down the remaining foam into some nice mountains/valleys and add driftwood and places to plant my fauna. Paint it, give it texture and color. Then I can start working on the water. I'll add water, heaters, powerheads and begin cycling while I let the plants up top get seated and begin growing. Thinking of stocking with RETF (Red Eye Tree Frogs) or Firebelly Toads...or maybe doing two or three green anoles instead.
The water will most likely be cichlids in some way shape or form. I haven't solidly decided what my stock list will be. So I remeasured the tank thinking that visually it didn't look like a 35g, and I was right. It's 48 gallons (25x25x18 /231 = 48.7g) So the way it is now, I get roughly 25-30 gallons of water out of this tank. I'll measure it out once it's actually full.
