i have this 24 gallon aqua pod that im starting up theres nothing in it but water and sand the temp keeps climbing up to 81 degrees when ever i leave the lights on their is a fan in the hood that draws hot air out and i was wondering if that might not be strong enough. its not the pump cause i checked. their was this cooler thing i saw some where that can be fully submerged and it lowerd the temp of small aquariums by a few degrees but i cant remember where it was.

thanks
