Well i finally got my floors set-up with some extra supports, and filled up my 125 gallon!! After leveling the tank, i filled it up, only to find that one side is not quite a half inch higher than the other side, actually closer to 1/4 inch. Is this anything to worry about? i know that if one side is way off, it can put extra stress on the glass over time...but with it only being off this much, is it anything to worry about?

I would say before you move all the fish and get set up, I would drain, re level, and then refill!

Well i believe i read it on this site, but i could be wrong...but ive read that when leveling a tank, as long as its inside the 2 black lines, its ok. And everything was in the black lines. I checked several times, cuz im paranoid like that lol. Would you still recommend emptying and re-leveling?

as long as it is in the black then I guess you could leave it... I have had them like that and all was fine...

Sounds good. Thank you much nicki! I just wanted to double check on this. I get way paranoid about things like this lol. Thanks again! I appreciate the speedy response!
