Please excuse my complete lack of knowledge here all . I love these vavariums I'm seeing and would love to make one myself. I've been reseaching dendros for a few days now and all I keep reading is how clean you need to keep things, makes sense. So my question here is how the heck do you clean these set-ups? Looks like everything is foamed and stuck to the tank, sonds like a nighmare when cleaning time comes around.
