If the tank is actually filled to the brim (tanks never are) the water would weigh 8.35lbs x 30gallons which is 250.5 lbs. To obtain an accurate total weight you would have to add in the weight of the sand/gravel substrate, and the rocks (decore) and the weight of the empty tank. Then you would subtract the weight of the top 1 inch or so that is always left empty.

120 gallons of distilled water weighs 960 pounds. The weight will be 960 pounds plus whatever the empty tank itself weighs.

What does a gallon weight?

It depends what's in the gallon. If the gallon is empty, it weighs zero. If it has air in it, it weighs a little bit. If it's full of water, it weighs about 8.4 pounds. If it's full of gold, it weighs about 160 pounds.


If you climb into a 55 gallon drum full of water will the weight increase by your exact body weight?

Yes. As long as you don't spill any of the water out of the drum when you get in, the total weight of the drum and water with you in it will be equal to the weight of the drum and the water plus the weight of you, separately. It doesn't matter if you float or sink. It will weigh about the same as it did before you climbed in. First, the answer above this one is wrong because you cant climb into a full 55 gallon drum without spilling water. As you enter the water, you will displace that volume with your body which weighs close enough to water to weigh near enough the same minus the amount of bouancy.


Do fish ever get full of water?

They are always full of water!!


Will a tank full of water and a tank filled with water and fish swimming weigh the same on a scale?

That depends on the weight of the fish as compared to the weight of the water their bodies displace. If it's a heavy, dense fish, then the tank with the fish would weigh more. If it's a light, less dense fish, then the tank with water only would weigh more. This assumes that the water displaced has been removed from the tank, right? If you are adding the fish to the water then I think it should increase the weight regardless of the density of your fish. The question then might be, does the fish weigh less when it is swimming than it would on a dry scale?


You have a 3 gallon pail and a 7 gallon pail how could you use these pails to put exactly 8 gallons of water in an aquarium?

Easy. Fill the 7gal pail to the full mark (7 Gallons) with water. Then pour, from the 7 gallon pail, water into each of the 3 gallon pail up to the full mark. The remaining water left in the 7 gallon is 1 gallon. Pour this gallon into the aquarium. Fill the 7 gallon pail with water, again to the full mark, and then add to the aquarium. 1 Gallon + 7 Gallons = 8 Gallons.

How many ounces does one gallon of water have?

1 gallon has 128 fluid ounces in it, regardless of what substance may be in it. Its weight depends on whether there's anything in it, and what the substance is. If the gallon happens to be full of water, then it weighs about 8.3 pounds (on Earth), but even that depends on the temperature. You can always be sure that 1 gallon is the same amount of space as 128 fluid ounces.


Does a gallon of liquid water equal to a gallon of liquid water with ice cubes?

No, not exactly. Water expands when it is frozen, so a gallon containing only liquid water and a gallon containing a mix of liquid and frozen water will have different volumes when the liquid melts. That is, the second gallon will be less full, as the water contracts when it melts.
