Lighting — I used to have Radions since Gen1 thru Gen6. My other tanks are Radions G6 Blues but I got (twelve) Orphek OR3s on the new 450g (8x3x2.5) tank. Have you decided on make / model yet? If open top, you might need to build some light racks perhaps?
The leveler is a welcome addition! I recently purchased an IM 112 lagoon and leveling feet would have come in handy. I'm very happy with my IM tank and happy to support a local company - I hope this one works out well for you, too.
