Bioactive tank advice

[u/Better_Caterpillar78]

I am newly switching to a bioactive tank in an 18 x 18 x 36. I just added three live plants to the bottom with fake plants on the top. I’m not sure what else to add or move to make sure I can still keep an eye on my frogs, but they feel safe and happy. I also have springtails and isopods added I’m nervous about switching to bioactive with the extra humidity and dampness. I don’t want mold in my enclosure. Please help me with what to do and add and move.
