Pool filter sand for goldfish aquarium9/25/2023 Challenges of Using Sand Substrates in Aquariums Bottom dwellers often enjoy digging and hiding in it, so it’s important that your substrate is safe for these delicate fish and invertebrates if you’re planning on keeping them.Your substrate also provides anchorage for live plants and supports root growth and their uptake of vital nutrients and minerals.Substrates support the growth of the “good” aquatic bacterial colonies that help regulate your tank’s Nitrogen Cycle and break toxic ammonia and nitrites into safer ( but not safe) nitrates.While it’s obviously a key component in your tank’s appearance, your choice of substrate also has a direct impact on the water chemistry, potential plant growth, and even the well-being of the animals in your tank: 6 Should You Use Pool Sand in Your Aquarium? Role of Substrate in Aquariumsīefore we delve into the pros and cons of using pool filter sand, let’s take a second to talk about the function of substrate and the role it plays in your aquarium’s health.4 Making Sand Substrates Work For Your Tank.3 Benefits of Sand as Aquarium Substrate.2 Challenges of Using Sand Substrates in Aquariums.Consider a different aquarium shape despite the fancy look of such a tank. Spherical aquariums are usually small tanks, fish have to swim in circles, which is unnatural for them, and it's hard to put a filter into such a tank. Just remember that such tanks are not appropriate for keeping fish, and in some countries, they're even forbidden! Is your aquarium in a custom or bizarre shape? Check out our other tools, such as the triangular prism volume or spherical cap calculator, which can find water volume for spherical aquariums, also called fish bowls. Tan(β) = 0.5 × length / (full_width - width).įor the aquarium with a bow front intended to stand in the corner, the formula is:Ĭorner bowfront = (0.5r² × (α - sin(α)) × height)/2 You can calculate the angle α with α = 2π - 4β, where β is an angle expressed as: Where α is the central angle of the circular segment, in radians, and r is a radius of a circle. You need to have given four dimensions: height, width, length, and the full width of the aquarium, and then you can derive the final formula:īowfront = height × width × length + 0.5 × r² × (α - sin(α)) × height, It's handier to use radius instead of diameter in this last case: diameter = 2 × radius.Ĭalculating the volume of the bowfront aquarium is a bit trickier. Quarter cylinder = π × radius² × height / 4 To determine the volume of the quarter of the cylinder, take a fourth part of the full volume: Half cylinder = π × (diameter / 2)² × height / 2 Your fish tank is a half-cylinder? No problem, just divide the formula above by 2: If you want to calculate the water volume of a cylindrical aquarium, use the formula for cylinder volume: Our cube calculator can help you calculate this volume easily. The cube-shaped aquarium has the easiest volume equation – simply raise the edge length to the third power: Our rectangular prism calculator will make this calculation simple. To find the volume of a standard aquarium, calculate the volume of a rectangular prism (also called the volume of a box): If you want to calculate the aquarium size manually, you can use the different formulas for volume, depending on the tank shape.
