leveling bigger tanks - shims or concrete?

would like your idea here... gracias

200 gal on left, 400 gal on right

concrete at such a thin layer would prolly crack, yes? but shims look kinda mickey mousey...

Forget the tank, I want more pics of those trees!

Another option would be to add (appropriately rated) leveling feet to the bottom of the steel stand and do it that way. I would probably use shims. I don't think it would be easy to level with concrete.

I think it depends how far it is off, but shims would more then likely be the way to go. Btw, u definitely wouldn’t want to use concrete. If u wanted to go this route u would need to use a floor - self leveling underlayment

ok thanks guys, i used shims, the 400 gal is on the rack!

* after 4 days of scratch removal nightmare, whew.

just a note, for this used acrylic tank, novus 3 worked following 3000 grit. i used straight muratic acid, then with a electric sander: 800 grit on bad spots...

and at the sand line down 1000, 1500, 2000, and this janky 3000 grit pad from autozone, which to my surprise, worked insanely well. then novus 3 and 2, whole tank, applied with microfibre attached to the electric sander (that squarish one). everything employed the electric sander, woulda died more without it.

Seconded! Certainly not a bonsai expert, but the one towards the center looks old. Impressive.

Yeah those are cool trees.

I have once leveled w/ crete but that was because it was a very uneven slate floor and the deviations were just too great, so I laid down heavy plastic sheeting to protect floor, made a form/frame, mixed it right in the living room.

My floor was also out 2" in 4', so mine was pretty dramatic, so basically a form 2.5" on one end and a half inch at the other, it held fine and 2 years later I was able to pull it up in one piece clean.

Yours does not appear that bad though, shims would probably be the better call.

Had a 1/4" gap towards the middle of my aquarium (sloped basement). Pumped concrete into it with one of those toy water guns
