well i am a floor layer and only things I can think of is that any water spillage or drips will work their way into the floor and ruin it slowly. so maybe think about putting some kinda mat around the tank area? another thing is the laminate floor expands back and forth as it changes temp so if there is alot of heavy pressure points pinning it down it might not move properly and could cause distortions. only thing I can think of to combat that is to put your stand on a sheet of wood cut to size with a foam mat underneith it to keep your floor from damaged by the underwood. that would help even out the load on the laminate.
hope this helps
