Hey Gujustud,
Yesterday, my carpet guy measured my place for the new carpet. Turns out he is reef adictted. Sooo he offered me various kinds of rubber "tiles"
to put under the tank stand. I think they are samples or testers or something..... Check out a carpet place near you and see if they have anything that will work. Mike (carpet guy) said you don't want to buy it as it is expensive but usually tanks need like less than 2 sq meters so I'd go for scraps and or samples
Good luck
