I'm only allowed to keep fish tanks in the basement, and it's furnished with nice tiles do it doesn't matter because you can just mop it up without damage to the floor. I don't pay for utilizes. In my other posts I also was told not to worry about dosing. And for filtration just don't go with major brands, I went with highly rated protien skimmers and wave makers that work really well. I'm just glad I got the lights with the tank. Also for a month of water changes it cost 20 dollars of salt which isn't to bad. I like to feed heavy so I pay about 100 bucks a month for all my tanks and pond. The fish arent to bad either honestly, i found an online seller that gives money back, qts, and is cheaper that live aquaria or lfs. The only thing that will suck is being addicted to this hobby for the rest of my life.
