Ok, I just got a 20gl long today (yipee![img]http://www.**********.com/iB_html/non-cgi/emoticons/wink.gif[/img], and i was wondering what kind of cover i sould get. A glass or plexiglass cover.
I know that plexi glass will get warped with the heat from the tubes, but i was wondering how long that takes.
I have heard glass is a good cover, but is more dangerous than plexi glass.
Also, i would like to know an estimate on how much each cost per square foot and such...
Thanks in advance!!!
