    Need help with cold temp

    My 200 gal redsea 750 xxl rimless is sitting right in front of a ceiling to floor window, width of window of it's entire length. Room is also cold, poor insulation in the entire room. I'm having a hard time keeping the temp up even with 2 200w in sump and 2 300w in dt. Sump temp is nice and toasty at 78-79. DT is barely 74-75. Any suggestions on what to do to keep my temp at a rock solid 78 besides having to redo the entire first floor of the home. Also, seems running two tanks has officially maxed out the electrical capacity the bottom floor can take. Adding a space heater will trip everything out.

    was going to suggest an oil heated heater they sell at home depot, but you would need a heavy extension cord run from another part of the house. You could also pick up styrafoam
    from HD and cut it to fill n that big window. Would definitely cut the flow of that cold area

    I'm having a hard time to believe that 1000 watts of heaters won't get to your tank from 75 to 78.
    What's your room temp and does you whole house heater works correctly?

    My suggestion is if your sump is good and tank not switch the thermometer from your sump to tank and tank to sump.
    Reason for this is that I think you get a false reading.

    Cover your tank will also help with at least 2 degrees.
    If that doesn't do it you can still pick up a roll of radium barrier, use the attic foil as there are 21 different radium barrier materials, the attic foil reflects the heat from your tank back into the tank if you use it right.

    I have a single 300w on my 200g and it stays above 77.3 in the am. I run the lights later at night to keep it warmer during the night.

    Punisher,
    What lights are you running? I had 1 300w heater on my 200g and it seems to run a lot. It does keep the temp at 77.5 though. I added an additional 300w to reduce run time.

    I was looking for a post like this It is minus 20 C outside minus 30 with the wind chill and I cycled to work today (I live close towork) . You have to be a toughy when you work with Nurses lol. I am only using 250 watts total of heat and those 3 heaters are not on all the time. I cover the top of my aquarium with insulation along with 3 of its sides. I am away from my home most of the time so need to keep it toasty warm. Happy New Year
