Lifting one side of a tank to level

[Akhval]

Hey guys!
So i have a 65.4 aquarium and when i initially setup my tank, i thought it was level but now i realize that it isnt. After checking level, i realize that i have to lift one corner(front right) by maybe 0.25 inch to level the tank. I tried hammering in shims to no luck.

My question is, without draining my tank (atleast not 100%; could do 25-30) how can i raise the front right corner? My lfs did tell me they use a product from amazon to do this and also move aquariums. Picture included below. It is rated for 3800kgs.

Is this doable, or dangerous?

I needed to level a 120g tank. I took the floor jack I use to change tires on my car. I put a 2x4 along the inside of the door in the stand and then another 2x4 from the jack to the 2x4 at the top of the door. I slid in a spacer and it worked perfectly.

I cant picture that in my head for some reason. Did you empty the tank?

OK. A floor jack at the end of a door on the front of the stand. A 2x4 going up from the jack to the inside top of the open door. Jack it up a stroke or two, place the spacer and let it down.

The jack can lift a car, so it has no problem lifting the full tank. Just be careful not to jack it so high the water spills out the low end!
