Rough layoutSounds like an a really nice looking display. Have you considered going with a radiant heating solution? My system is ~1700 gallons and radiant heating is the way to go to not only save money but also avoid electrical heater disasters due to heater failures. I can speak for everyone in saying that we are looking forward to seeing some pictures. I would be interested to see how your tank and fish room is laid out to see the space where humidity controls are being installed.
