Does anyone have any experience with chillers? the reason why is we are setting up our rec/ fish room....we are installing a pellet stove in the room and i am worried about the heat that it is going to make....just wondering if a chiller is the way to go, or maybe someone has idea on how to control the heat in the tank.....the new tank is going to be in the 140 gallon range...we are putting two 400 watt MH and a VHO set aswell
