Honestly what I did to my buddies was I jacked it up put sand underneath it you can use filler sand or anything really and it looks like you're off by about a half a dude so I would use the half inch by 12 square pavers pavers in the most unlevel but in this case you need to make sure you have enough sand under the whole thing to keep it even all the way through so it's a job and half I highly doubt you can pull that Jacuzzi out easily to get under there to pour enough sand because if you raise one side the middle is going to be not touching ground it's honestly an annoyance in your case Case if it's not bogging down your pump or anything I wouldn't even touch it to be honest
