| You are definitely going to need a chiller, the lighting will add a lot of heat to the tank.
I would probably get one small heater is to be safe.
you will need to invest in a good ro/di water purification filter, all of your makeup water and top off water should be ro/di water. using water from the ocean or the canal would be a no-no.
as far as the floor goes you would probably be ok on the tile but not knowing the type of tile you have I would probably recommend having a professional look at for you.
