I have a Fluval edge that i removed the top from and use as a standard open top tank now. I plan to plant it heavily and add co2. Still trying to decide what lighting to go with. Do you have any suggestions? There is a LED fixture for smaller tanks at the LFS but i think it is meant for reef tanks, and its 80 bucks! Thanks more than i spent on my dual t5ho fixture for my 20 tall!!! Thanks for your time guys, looking forward to your responses.
