Aquarium calculator can be used to calculate the volume of water in square, rectangular, cylindrical or hexagon aquariums. Water volume is needed to ensure you treat your aquarium with the correct dosage of medication and fish stocking levels. You can convert the dimensions of your aquarium (in inches or centimeters) to a close approximation of its volume (in both U.S. gallons and liters) quickly and easily. Features: • Calculate the volume in square, rectangular, cylindrical or hexagon aquariums. • Calculate the water needed 1in [2.5cm below aquarium height]. • Calculate aquarium surface [for table top preparation]. • Calculate sand need [1 in / 2.5cm thick] for the aquarium. • Recommend amount of fish [with various sizes] which aquarium can support. • Recommend pump size with flow rate [Liter/Hour or Gallon/Hour]. • Recommend pipe diameter which use with pump for better water flow efficiency. Aquarium calculates tank dimensions for your rectangular fish tank in either centimeters or inches to both gallons and liters. This conversion can help you to determine appropriate tank population, and whether you have enough space for the fish you are planning on getting. When selecting the best filter and pump for your aquarium fish tank, you must consider: Which type of filtration system is most suited for the aquarium you want, what is the desired flow-rate for your aquarium livestock, what additional equipment will be set up, and what sort of plumbing will be installed. Starting with filtration, you will need to know: 1. The Volume of Your Aquarium Assume that your aquarium capacity is 100 litres. For the cleanest, healthiest tropical aquarium set-up, we recommend that all the water in the aquarium flows through the filter 4 times per hour. 100 x 4 = 400 This means that the preferred filter for your fish tank has a flow rate of at least 400 litres per hour. Your pump can only perform as well as your plumbing system allows it to. A common mistake contractors make is that they install pipe that is too small and blame the pump for not yielding enough power. Never size your plumbing based on the pump outlet rather always size your plumbing for the amount of water your pump is generating. Add new stock slowly! Your tank may support this many ultimately, but don't stock them all at once! Stock a few fish at a time, a week or more a part, to give the aquarium residents time to adjust and the biological waste processing bacteria time to expand to meet the new demand. Too many fish, even the "right" fish, can overload the natural bacteria that need time to become established. Thanks for your support and do visit nitrio.com for more apps for your iOS devices.
