I get those jitters every time, even though I've set up tanks almost a dozen times now (3 new ones and two that were used, some two or three times), every time I get a new one especially though, I always worry it'll leak or the bottom will crack or something. I know it won't but it's hard not to keep checking regardless. With my biggest yet, a 55g, I was checking everything three times over with a leveler to make sure it was perfect so it didn't bust and spill all over.
yesssss I know that feeling I am refilling a 130 gallon at the moment and just know I will wake at 3am worrying and will have to go check all is ok and my living room is now not a pool room
Oh, I'm okay now. I've had it set up for about a week with the only water loss from trying to get the cannister filter hooked up. Nothing major, no flooding but that first few days...
