I am using a combination of Lexan along with a screen top. The light bulb/fan idea just doesnt work like I thought it would. My 150w red bulb is struggling to keep temps at 78 degrees. Might try a ceramic and try to control the airflow with barriers. My next step is to make another plexi 3/8 lid with a cut out for the light fixture. Then using a hole saw to remove a few pieces of plexi that I can remove/replace to control temp. Thanks for compliment Kevin. Im really enjoying the tank Ive made. The plants seem to be doing fine, but it has only been a week. Just planted a new water plant also... I know ABF can be hard on plants. Im just not sure how to interpret you comment about the plants. Im assuming you've had some direct experience with a Pixie tearing up plants? Please feel free to elaborate. I am still very new at this.

Thanks,
B
