I have usually kept my tank at 76 degrees, but recently turned my heater down a couple of degrees to slow the growth of my snails.
Unfortunately, the temperature seems to be shooting up now! I realize it is summer now, and I don't have A/C (not needed, because I live in Seattle), but it hasn't even been above 75 here yet.
This morning, right when the aquarium light turned on, it was just below 80. When I got home from work, it was about 81! My tank has never been this hot.
The heater is now turned all the way down. Also, it doesn't even get that hot in the room, as I leave the window open all day long.
So, does anyone have any ideas on how to maintain a cooler water temperature?
By the way, I have the light on 12 hours a day, and the aquarium is near a window, which has a quilt covering it (except for a small portion where the window is open.
Thanks, in advance, for your suggestions!
