Now the new chiller is in place and it chills the water down to 76deg in about an hour. So far it looks like everythings under control. ESU has really impressed me with their customer service. now if can only get my hands on another control unit to remote mount in the house to keep tabs on things. Over the weekend we ended up building a room around the tank and plumbed in some a/c to the room. I'm now down to a 1.5 car garage so it i ever end up buying a half a car it will all work out.
