Updated Fish Room as of March 2011

I just finished my 2 pine wood rack for my new tanks that arrived last weekend. I also finalized the setting of my tanks. The rack is now up and running with tanks and fish. I now have 40 tanks and 7 plastic tubs for grow out. I still have all my heater plugged in as of the moment. I'm still debating on insulating the basement/stockroom converted to fish room with new floor heater and checking also if it's gonna be same expense just using the heaters on each tank.
