You can enter the height of Substrate 1 if you have it in your tank. You have the option to specify the type of substrate you have in your aquarium, such as sand, gravel, fine gravel, or soil. This calculator considers the density of the substrate to determine how much water it displaces or occupies within the tank. In your rectangular or square aquarium, the substrate at the bottom significantly affects the total water volume. This information helps you plan your aquarium setup accurately, ensuring you have a clear understanding of the water volume and the impact of the substrate. Water Displaced by Substrate: This is the amount of water displaced or occupied by the substrate in liters.Current Water Capacity (with substrate): This reveals the effective water volume, accounting for the displacement caused by the substrate.Water Capacity (without substrate): This tells you how much water your aquarium can hold, excluding the substrate, in liters, US gallons, and imperial gallons.The calculator provides you with three key pieces of information: Once you've entered all the necessary details, click the "Calculate" button. You can also add information for Substrate 2 if you have a different type, for example if you use soil and cap it off with another substrate.Choose the type of Substrate 1 from options like sand, gravel, or soil.Enter the height of Substrate 1 (if present) and select the unit of measurement.If you have substrate in your aquarium, you can specify the details here. You can choose your preferred unit of measurement, such as inches, centimeters, or feet, for each dimension. Provide the length, width, and height of the tank.You start by entering the dimensions of your aquarium.
It provides you with essential information about how much water your aquarium can hold, accounting for the substrate's presence. This calculator helps you figure out the water capacity of your rectangular or square aquarium, considering any substrate like sand or gravel at the bottom. If you have a 75, add 75 gallons’ worth of salt if needed, dose medications based on 75 gallons, etc.Determining Aquarium Water Capacity with Substrate Even medication or salt dosing has wiggle room and it’s impossible to calculate the actual volume of water in a tank when you consider substrate, decorations, rocks, filters, etc. The difference between 75 and 79 doesn’t change the heater you need, the filtration you need, etc. And two, the dimensions are the outer dimensions and the internal dimensions are slightly smaller. One, companies round the volume (75 makes more sense than 79). For example, the calculated volume may be 34 gallons but the tank may be listed as 30. This would also apply to tanks for African cichlids where you will also have a lot of rock work. This gives you enough space to set up a stable rock pile as well as allow enough width inside the stand for a 12″ wide sump. If you are interested in any of the other tank shapes, just ask your local shop what all they can get in for you.įor reef tanks, I highly recommend a tank at least 18″ wide (front to back). The special shapes cost a lot more per gallon. I prefer the standard tanks below because you get more volume for your money. This list does not include bow fronts, hexagons, cubes, columns, etc. This list includes the basic/standard rectangular tanks. Most come in multiple color options and most of the larger ones are available pre-drilled with built-in overflows (some overflows are built in to the corner, others are on the back). Not all of the tanks listed below are available from both Aqueon and Marineland. I do not have a preference for either brand over the other, in my experience they both make high-quality, reliable aquariums. Below are the standard rectangular fish tanks made by Aqueon (formerly All Glass Aquariums) and Marineland (formerly Perfecto).
