rubbermaid liner
I am thinking of preventing any major catastrophes.
I am setting up my sump and will make sure that I have enough room for backflow in the situation of a power outage.
However, I would like to put a rummbermaid liner or something similar under my sump. It is a 55g (48" long)
Any recommendations?

I have been throwing around the idea of using a type of thick plastic liner such as a pond liner to line the bottom of my tank stand so that if something would to happen i would have a 3-4" pool that water could collect without getting on my carpet.
