When trying to get the dosage of a certain medicine or product in your fish tank, you always need to use get a certain concentration, which is based upon what you already have in the water, which is why a fish tank calculator are so useful.A fish tank calculator will simply take the dimensions on your fish tank and calculate the volume of water that is present in it. In an rectangular block shaped fish tank, you multiply the dimensions of each of the sides and then multiply that to the height. Make sure that you put the values in the same order of dimensions (inches x inches x inches or cm x cm x cm). As for a fish tank that’s a cylinder, you need to multiply the number Pi with the square radius and then multiply to the height. Just on a side note, for these measures, assuming Pi as 3.14 is perfectly acceptable. If your fish tank is a sphere, then you’ll need to multiply 4/3 with Pi and then that with the cube of the radius. (Note that the square of the radius is nothing more than r x r and the cube of the radius is r x r x r). |
