Here is my setup.
At the top is my reservoir bucket with a float valve to the water filter and a bulkhead connector + quick release/connect to the water lines.
Here is an Individual level pic. Each level requires a Tee that branches off to the water supper itself.
I recommend freedom breeder sippers, but you'll need the mounting clips from reptile basics.
Basic rundown..
-Reservoir bucket
-Float valve (if not manually refilling)
-Bulkhead adapter
-Quick connect / release from bulkhead to water lines
-Tee, sipper & mounting clip per level
-water tubing
Hope this helps!
