Under tank liner to protect floors

[drawman]

Just curious what people may be using under a tank stand to protect their floors. I moved into a new apartment building and want something to protect against any spills. I wonder if there is a rubber floor liner or something different? My tank is a Red Sea Reefer 250 FYI.

There are mats out there to put down that will absorb spills. I think there is one big enough for the reefer

Oatey PVC shower pan liner. Saved my floors several times even though my sump has never flooded and highly recommend it.
