Pools - I have read a few posts about these, so I know one fw, one sw. I have 4 small, but good sized containers, 2 for each pool, so there's an extra underneath as I've seen mentioned here. What materials are safe for the bottom? Can I use the glass "rocks"? Would they have to be siliconed (is that the right adhesive?) to the bottom, or could they remain loose? What materials can be used for climbing out? I've seen fish nets (?) and needlepoint canvas as suggestions. Should I put something sturdy in part of the pools so there's a shallow and deep end?
Multi-levels - Are suction cups the only approved method to achieve multiple levels? I'm thinking moss pit and shell shop would both be good as upper levels? Would these things need solid sides, or would sides with holes work? I imagine solid because their legs may get caught in the sides if there are holes?
Can the cheap dollar store bags of decorative shells be used for anything?
I "only" have a month-ish before we can hopefully find some crabbies to get this all set up.
