My house is 62 yrs old. I have 3/4” oak hardwood floors. I took a 4’ x 8’ sheet of oak furniture grade plywood and put 1/4 round on edges. Sealed with Minwax polyurethane. It’s been there for 11 years. I’m scared to see what’s there when I upgrade my tank next year. I knocked over a 5 gal bucket SW about 5 yrs. ago
