I prefer the ideas above for making as little floor coverage as possible, and moveable (sliders) at that. ]
I see the OP point, too. I also have 125 gallon tank, 20 gallon sump on newly finished 60 year old real oak hardwood floor. Also a 72 gallon bowfront with a 20 gallon sump over the same floor.
Both of the stands are DIY, and have feet the full length of the tanks.
I glued felt under the stands. I was of 2 minds while I was doing it.
a) Will hold moisture, wick it in, but it would also evaporate right back out.
b) Felt against the hardwood would protect it from getting scarred.
Point a) was a wash (pun intended!) Felt might help the water get in, but would just as easily let it back out. Point b) became the deciding factor.
Yeah, I'm mostly hoping to just prevent water from getting underneath there to begin with (not the best of plans, but...) Once I get it set up, I may see about putting some sort of removable caulk, or even weather stripping around the edges to prevent the occasional spill splash (more likely from me carrying something then the tank itself). from creeping under.
I made some adjustable feet with sliders from my stand out of t-nuts, elevator bolts, and some furniture sliders. I'm pretty happy with them right now, and they hold the stand something like ~1/4" off the floor, and hopefully will work better for leveling the tank then shims and such when I finally do set it up. The two on the right are finished, I had to sand down the edge of the bolt head a tiny bit to get a really nice fit with the sliders. The one on the left is pre-sanding (blue tape to protect the threads from the chuck).
