I have a 92 gallon bow front fish tank with stand that weighs about 175 lbs empty with salt water being over 8 lbs per gallon. There is 240 lbs of live rock a 20 gallon filter system plus pumps lights and everything else. That is well over a 1,000 lbs. It has been setup in my second floor bedroom for two years and have had no problems. I do have it on a load bearing wall so that probably does help. I think your good to go. Have a safe move. No pun intended
