F.S. mantis shrimp needs cool newl home. $300 whole setup

I have a 20 gallon long w/black silicone that is home to a peacock mantis shrimp, a turbo snail, and a dusky (yellow) dottyback.  Equipment is....eshopps 300-600 gph single u tube external overflow box, eshopps 10 gallon reef sump, heater,  mag 5 or 7 return pump w/ locline, coralife super skimmer 65, heater, filter sock and sock for carbon, 2-65 watt power compact light fixture w/moonlights,  2 powerstrips and a light timer, and a mag float.
     I have pics but not sure how to post them here...i will when i know how to.
The reason for selling the setup is because my house gets too hot and i dont have a chiller for this tank......so, if anyone knows of a cool home(lots of a/c...lol) let me know.
