Can I put a 15 gallon tank on a granite counter?

Or will this crack the counter?

    A 15 galon tank filled with water only, nothing else, no other items attached to it or in it that a fish tank needs, will weigh 170lbs / 78kg. 

    How thick the granite is and what grade of stone it is and what's supporting it and where / if periodic supports are under the counter surface matters. The size of the counter also matters and you didn't include any of that info. Since you didn't include any of that info I would suggest not putting a fish tank on it unless the structure holding the counter top is a very hard wood like walnut or maple or cedar and has some steel reinforcement. The counter top it self could weigh quite a bit depending upon it's dimensions. The other thing that should be considered and have concern is the floor. The floor needs to be strong enough to hold the counter, the counter's framing structure, the weight of the tank, and the weight of everything else you might have on the counter. 

    A 15 gallon tank isn't that large of a tank however when large fish tanks or even other heavy items like a piano or a billiards table for example are placed on a floor the floor has to be and is reinforced underneath by load bearing poles / floor jacks and extra beams are installed. Extra structure is put in to insure the floor is strong enough to hold all the weight. It might not happen immediately but over time if the floor isn't capable of holding all of the weight it's possible some really bad stuff you hopefully prefer avoiding can happen. When a floor warps or cracks it effects the integrity of the entire building and can be extremely expensive to correct. 

    If the framing for the counter, the cabinets and all, is a really strong wood and steel enforced and the granite counter top is the standard thickness (lets assume it's around 6 feet long by 3 feet wide) that could be approaching somewhere near a ton (2000lbs) of weight, not including your stove, the fridge and everything in it assuming it's a kitchen, the table and chairs, all your dishes, pots and pans, etc...plus the weight of you and your family and guests standing and walking on it lets not forget. It's all weight the floor has to hold up. 

    With the tank filled with water weighing 170lbs then adding the gravel or substrate it will need (15lbs, 1 pound per gallon), the filters, the lid, the lights, other decorations, and fish, a 15 gallon tank is somewhere around 250lbs including all the stuff you might have in it. 

    Can your floor handle another 250lbs? Can the counter top hold that much? Maybe. Maybe not. Another 250 might or might be where it decides to give up.

    I suggest not taking that risk.  

    Reinforce the floor and the counter top structure before putting a fish tank on it.

      Do the math and use your heads before down voting. A gallon of water weighs approximately 8lbs. Multiply that by 15 (gallons) and add all of the weight from everything else a fish tank should have before evaluating this answer as wrong. These other answers are way off.

    Water weighs 8 pounds per gallon x 15 gallons = 120 pounds.  The countertop can easily handle far more than that.

    That's about a hundred and thirty lb with the tank. It will likely support the weight. Unless it's a very cheap countertop

      You're about 40lbs off and that can make a difference.

    Yeah. The counter will be fine. A 15 gallon tank filled with water weighs 120 lbs. and distributes it over 2 square feet, which is only 60 pounds a square foot or 7 ounces per square inch. A granite counter top will easily withstand many times that weight without breaking. People stand on granite counter tops all the time, and the weight per square foot pressing down on their feet is more than what that 15 gallon tank will do.

      The water it self weighs 120lbs. That's not including the tank structure, gravel, decorations, fish, filters and the water and filter cartriges in the filter. We not only need to consider the surface, the floor is most important. The structure of the surface frame matters too. Granite is heavy.

    Sure you can. Some Thanksgiving turkeys weigh more than that.

      No way in hell a Thanksgiving turkey weighs as much as a 15 gallon fish tank full of water with everything else that's in it. A fowl day bird usually only weighs 20lbs. A 15 gallon tank with all the decore in it is approaching 250lbs.
