Is your trim loose, if it isn't, I'd sure be concerned with the tank tilting back and forth.

Where is the tank located in the house concerning upstairs, downstairs. If it's upstairs did you reinforce the floor or place it on top of a load bearing wall.

the floor is cement with 1x4 laid side to side leveled and with ply wood on top and leveled. have had the tank befor i had the house and redid the basement and planed for the tank to be in that spot since day one.

Maybe shore up the side that is drooping with 2by4's. I really dont think your slab would shift without you noticing some new cracking. I would check out those stands and make sure they are still structurally sound. that is where the problem is most likely located.

put a level on it.It sounds like your tank is sinking.You have to move the tank and redo your floor.I have seen additions on houses sink and settle.If your tank isnt level look out it could exsplode on you.Dont wait fix it now
