New setup
Last night I finished setting up my first ever bioactive terrarium for my Black Pastel Ball Python. He's in a 48 × 24 × 18 (90 gallon) enclosure.
I started off with a layer of clay balls, but after realizing that there weren't enough on super short notice, I was able to get some filter gravel (heavily rinsed before adding). A few inches of that, topped with some regular water + water squeezed out of our fish tank filter to kickstart the bacteria. On top of that was the sheet of mesh to separate the drainage layer from the substrate layer. Then I mixed coco fiber, Zoo Med forest floor cypress mulch, Zoo Med reptisand, activated charcoal, Maple/Linden leaf litter, and sphagnum moss. I planted 3 Pothos plants and a curly fig. On top I added more sphagnum moss that I dipped in water to hydrate and then squeezed out, and a gallon of Maple/Linden leaf litter.
I added what I have started of my springtail culture (not much) and over 50 isopods including powder blues, porcellio lamellatus, Armadillidium nasatum, Armadillidium versicolor, and cylisticus convexus. I also sprinkled some brewers yeast where I added isos and springtails.
PLEASE let me know any tips, what I should do, what I should've done, how I can help this ecosystem start, and even if I should order more springtails because I only ever saw around 5 at a time in the culture I started.
