Cold Water?

[fruitbooter44]

all over the market there are various heating equiptment for the fish environments, however certain fish for example a brook trout need cooler water to thrive, does anyone have any ideas on how to keep water in a 30 gallon tank in a room that stays around 65-75 degrees to a water temp of 50-60 degrees?

Aquarium chiller. Expensive though http/www.aquariumguys.com/chillers.html

Try a large box fan pointed at the tank
