Then painted the rock wall with several browns, reds, yellows, oranges with non-toxic accrylic paints. this took a while as well as it took several layers to get the natural sandstone look i was going for.
After i was satisfied with the painting i sealed with a couple layers of water-based mod podge and threw quite a bit of natural sand at it while it was still wet & tacky for some more color-variation, to cut down on the shine of sealant, as well as give my leo some good traction while climbing.
Masked off & painted the outside of the tank black to hide the styrofoam innards of the rock wall.
Re-installed the aquarium trim as well as installed the "E" chanel for the bypass doors in front.
(also played around with decor arrangement)
Sadly i don't have pics of the process, but i built this lightbox. it's basically just a wooden box with four porcelain bulb sockets wired into toggle switches. Painted the outside black to match everything, inside flat white for the best reflectiveness.
Built the stand. 2 x 4 frame sheathed in 1x4 pine.
Built-in dimmer switch for the UTH.
Built-in risers for excess heat ventilation from the UTH.
Painted black like everything else.
I don't have pics of this, but after the sealing of the walls i basically just smeared a good amount of grout onto the floor of the viv. i was initially going to do a large custom tile, but i wanted something natural looking while not subjecting her to the risk of impaction as she likes to hunt. it's hard to see in the pics, but it really just looks like a slightly compacted natural loose sand substrate.
Then just threw the doors on the front, decorated, gave it a week's dry-run to test the temps, humidity, etc. and here she is all done!
My gecko loves it! i highly recomend anyone to doing this. it's a lot of fun, very rewarding to see your pet enjoying it.
