I have a 30 gallon aquarium with a Bio-Wheel type filter rated for 50 g. I live on the fourth floor in my apartment building and the aquarium sits on the floor. I take care of a large Orange Orada and a large Black Moor. I want to reduce my electric consumption so I am trying to avoid running the air conditioner as much as possible. The problem is that when outside temps are in the 80’s and 90’s (I live in Minneapolis, MN) the room temp. although lower than the outside temp is still high. I have 2 of those sticker type thermometers on the tank and I have seen the temp range from 70-84 degrees. I would like the tank to be in the low to mid 70’s. Any ideas on how I can keep the temp down on these hot summer days??? I keep the hood light off all day and at this time I have a small fan blowing across the water surface to cool by evaporation. My only other idea is to get some of those reusable ice packs, put them in a ziplock bag and float 1 or 2 in the water. Thank You!!!!!!
