I have a Solana with a 250W SunPod for lighting, and to regulate my temp I use the dual AZO Fan (30$ online) to blow air on the surface and it keeps it down to 78F, otherwise it would be around 83-86, house temp around 73F. If you decide to use a fan fix the temp, make sure you do get an Auto Top Off unit since it will evaporate around half a gallon of water per day.
Here is a link to the actual fans that I was talking about:

There is an online vendor here in Atlanta that sell this Fans but it looks like he is out of stock right now. His web page is [IMG]http://www.aquabuys.com">www.aquabuys.com</a>, give him a call and he will get u some for sure, and you wont pay shipping since you can pick up at the store haha :thumbs: , I hope I wont get in trouble for posting online vendors links.
