Well I had it up and running today, and the temp is about 80.5F with a floating thermometer. So it drop it 1.5 F or so. The water in the HOB filter is closer to 80. This is with a closed lid lifted off the tank by about 1/2 inch and the back porotion opened. (the lid is a nanocube 150HQI lid) on my 28g biocube.
It does work for what I need its still a bit to hot for me but hopefully it will stay like this now for the summer, but I'm gonna have to slow down the Hob pump to make it chill a bit better, or find a bigger peltier ( this one is 1.5" square)
So for about 30 buxs I droped, I'm quite happy with the way it turned out. So now what is the best way to slow down a HOB pump?
Well maybe it off to EBAY for a bigger peltier as well.
