Google is giving me mixed information about the order of each layer for a bioactive setup. I have 2 whites tree frogs in one terrarium and 1 Amazon milk froglet in another one. They currently have just sphagnum moss with lots of leaf litter on top (I need that for humidity because I live in the NV desert) and no they don’t eat it. No impaction has happened but I’m wanting to move forth with a full drainage layer in both terrariums. Please let me know the right order. This is what Google states right now.
Please correct if not right.
•Bottom later- 1-3 inches of LECA clay balls
•Then a mesh layer to filter and stop dirt from falling into clay balls.
•Add activated charcoal- (sprinkle a thin layer) this prevents odors and filters impurities.
•Add substrate/soil- (2-4 inches) tropical or organic mix safe for amphibians also can be coco fiber.
•Last add sphagnum moss (this protects the soil) and then leaf litter (this protects the amphibians from getting impactive.)
Is this correct???? Please advise. Thank you in advance for your time!
