I am currently placing my 120 tech into the wall. The tank will sit between to walls that make up my living room and office. My question is do you think the humidity will destroy the walls. I plan on a 50 gl sump and 30-40gl fuge. I saw a solar powered exhuast fan at home depot and was considering hooking this up to a humidity controller(gardening supply) to keep the heat and humidity down. Does this sound like a good Idea? I am thinking it will save the chiller from running constant.
