Fish Room Tank Temps. Ceiling vs. Floor

[Stash Beardsley]

Just wondering if anyone out there has any experience with getting their fish room heat more evenly distributed? I'm building racks with three levels. I have my room set to keep the middle tanks around 77F + or - a little. The top tank is around 82F and the bottom tank is right at 71-72F. I did put 4" thick of foam board under my bottom left tank last night because I thought the concrete floor was stealing the heat. This morning it was still matching the tank temperature without the foam right next to it. My next idea was to maybe place mini fans at the ceiling level blowing straight down to try and mix the cold air at the floor? Has anyone tried this or have any other ideas that work for them? I realize the top tank will always be warmer. Just trying to get the lowest tanks a few degrees warmer.

definately going to need a fan or fans to circulate the air.

Fans will help a bit, but there will always be a difference. Keep warmer temp species up top and lower temp ones towards the bottom.

I use fans to do this in all my fish rooms. Very slow speeds. Usually there is a 3-4 degree difference from the bottom tanks to the top tanks after that.

Thank ya, I mounted a Walmart fan from the ceiling blowing down. The bottom tanks have raised temp. and the upper tanks dropped some temp. Worked perfectly.
