I'm setting up a new IM 200 ext. As with many people, I'm having trouble getting it perfectly level. It was pretty level but after filling it and it settling, it's about 1/16" off on the front length. Is this acceptable or should I drain and relevel again? As the title says, tell us how off level your tank is and what size!
 
I was brand new to the hobby and pre r2r knowledge when I set my tank up. Made sure it was level width wise but somehow I over looked front to back and it’s just shy of a 1/4 inch off (basement floor.)

Throw on top I purchased the tank used off marketplace and it’s a Red Sea Reefer 350 so let’s say I don’t rest easy haha
 
I have a 90 gallon, 4 feet long, set up almost 2 years so far. It is maybe 1/16 to 1/8 off lengthwise. So far, all is good. But honestly, I do have in the back of my head to, at some point remove most rock and inhabitants leaving sand, some rocks that are in the sand, maybe 2 inches of water and all inverts so that I can better level it. Now most of the reasoning for this is probably just me with OCD, but some is out of concern in the long run.
 
I went over the top when I set up my S-1000. I bought a machinist level... my tank is level to .2" in 10,000ft :beaming-face-with-smiling-eyes::rolling-on-the-floor-laughing:
 
Lol! That even beats my ocd! I'm struggling with leaving it at 1/16" off on a 6 ft tank side to side!

While I would not like the thought of draining/etc to re-level, 200 gallons is 1600 pounds of water... I think I'd put in the work as that, seems to me, is going to put added stress on the low side of your tank.
 
I don’t make a huge effort to level a tank (Fully framed). I mount the tank on styrofoam and/or put the stand itself on a cushioned surface. It levels itself out after a while. My biggest tank is only 135 gallons though. Have it set up for 6 years so far. The rest are 50, 45, 45, and 75 gallons. I’ll make sure it’s in the bubble, but not worry about perfect.

How does it put added stress on the low side?
 
I try to get things a level as possible but im not making a huge project out of it. I don't think having the water line 100% level is critical . Having the stand solidly supported and no voids between the tank and stand are what is important IMO. A level waterline is awesome but a rim will hide if it isn't perfect and I put black vinyl tape along the top of my rimless tanks to hide the water line. I've never used anything more a carpenters level and had two 180g and a 150g running at once for upwards of 10 years with no issues doing it that way.

Lol! It's definitely making me stress a little. I guess it's because of all the horror stories of tanks leaking and people always stressing that your tank should be 100% level!
 
I'll take a pic when I get home and post to see if you folks think I'm stressing over nothing. Thanks for the replies so far!

I dont want to jinx myself my tank is 72w 36d 30t and went through

On November 30, 2018, at 8:29 a.m. AKST (17:29 UTC), a magnitude 7.1[1] earthquake hit Anchorage in South Central Alaska.[5] The earthquake's epicenter was near Point Mackenzie, about 10 miles (16 km) north of Anchorage, and occurred at a depth of 29 miles (47 km). It was followed six minutes later by a magnitude 5.7 aftershock centered 2.5 miles (4.0 km) north-northwest of the municipality.[6][7] The earthquake could be felt as far away as Fairbanks.[8]
 
Over 20 years, 125 gallon, about 1/8" off front to back and almost 1/4" off left to right.
 
I set it up the way it is. Seems like maybe 1/16" or slightly more from one side to another. In 6 ft I don't think that will cause an issue. At least I hope not! Got my aquascape done last weekend and everything is looking happy!
