I am shimming the stand. Stated that in the 1st post; I may have confused you by saying "I have to do this with the tank on the stand because its already plumbed and ready to go." I said because I have the fun of lifting the stand with the tank on it already. I just wanted to know if there is anything speacial i need to do since ive never had to do this or is it as simple as it sounds and I simply slip a shim and im good.
