Adusting water level with dual overflows

[HUKIT]

Tonight i filled my new 165 gallon tank with dual overflows. The tank is about 3-4mm off over 6ft so the water is only spilling into the left overflow. Is there a way to adjust the water level the megaflows or do i drain and shim? Thanks I'm starting to miss my canister's!!

I would want a a level tank but if you don't you could use acrylic to make the area surrounding the overflow 3-5 mm higher... as I said making the tank level is what I would do.

Just drained the tank and shimmed the stand. The front of the frame is not straight it's slightly deformed but the back of the frame is perfect. I never would have guessed 3mm would have made such a difference.

Make sure that one corner isn't lower then the rest!

If one corner is lower then the rest then you could have a twisting pressure on the tank and cause it to crack or break a seal...

I would use a level to make sure the stand is level before putting the fish tank on and filling it again.

Tank is perfectly level but top frame is slightly off when they molded the piece.
