Well, I have had my old tank down for about 5 weeks now and I think the title speaks for its self. All the craziness that I was experiencing with my old tank and the tear down has rolled over into the new system. While moving my frag tank I cracked it so I have to get a new frag tank. Ballast burnt out of T5 unit I am using and then while I was hooking up my LED hanging kit, one of the holders stripped out. Glad it was a test run and didn't fall in the tank. Last but not least and I could use some help here, I turned the lights on last night (tank is empty), when I noticed I could see light between the tank and the stand. It is not a lot of space, but the only place I could not see light is on each end. The sides are fine and I am going to check across the back tonight. The tank was set up on this stand before and the guy never had any issues, just wondering if over time it could be a problem. I don't know exactly how much space it is, I tried to use a wood shim just to check and in most places it will barely go in, just the extreme tip. Still got me kinda freakin out. Any advice is appreciated.
