So after reading Mike's recent thread and seeing my last power bill, I have determined I need to do something fairly drastic. My power bills have been steadily increasing and it is starting to seriously make me reconsider my long term viability in the hobby. I have a big setup and I know that comes with bigger power needs but I am certain that I could be doing something better but scratching my head on exactly what at this point. As most of you know my tank is plumbed to my garage which is significantly cooler then my house at all times of the year. I think my problem is likely caused by a heat/cool problem. Cool because the equipment is in the garage which is not very well insulated (though I have made some recent changes that will help this side), heat because I have a closed canopy and a tank that is right next to 2 windows. Unfortunately, I have no choice as to relocating the main tank but am hoping for some ideas as to how to better cool my tank. Even on some of the days over the last couple of weeks when it has gotten fairly cold at night, I can experience the heaters being on all night to keep the tank warm followed by my chiller kicking on (for a short period) during the evening to cool the tank from the heat generated by my lights. Aside from remembering to open my windows in my fish tank room every day before I leave for work and closing at night (which I will inherently forget to either open or close), any other thoughts? I have 4 icecap fans in the canopy but I fear they are either not set up right or not doing the job. I have 2 fans at the top that push out and 2 in the back that pull in with the theory that hot air rises but am thinking that even with this the hot air just gets trapped in the room and has no where to escape contributing to the problem.There has got to be a better way, I am hoping ,that doesn't require making huge holes in my roof or walls to run an exhaust fan to the outside but I fear that may be my only solution.
