Hello all new member here I think I am just being paranoid but having a custom tank built and doing the stand myself I have built the stand out of 4x2 timber untreated and it was built on a uneven floor so it has thrown my leveelness out slightly the front is within 3mm on the upright the back is close to 5mm the tank I am getting is a flat glass 10mm 325l and I have a slight dip in the center around 1 to 3mm I'm wrapping in 9mm ply hardboard and 12mm on the top I have enough spare to do another layer if needed
