Used felt pads under aquarium stand, mistake ?

[M4rtin]

I'm second guessing myself right now if what I did might cause an issue.
Just put together Reefer 250, it's on hardwood floor.
However I put felt pads under each leg of stand, I think around 10 all together, to slide it in easier in a tight spot, didn't want to scratch the floor.
Is there any downside on this ?

Why would you think this could be a problem?

Watched a video on making sure your tank is level, as unlevel aquarium can put stress point on one side and crack.
So that got me thinking if maybe felt pads might make reefer not level, maybe some will give in more than others.
Pretty much second guessing myself not to mess up in a big way A bit paranoid maybe

I'm curious too because I did the exact same thing.
