Buy on AmazonBuyers Guide: What To Consider When Buying Aquarium Sand
While the market is flooded with different types of sand to choose from, not every one of them will be suitable for your aquarium. As such, here are some of the crucial factors you should consider when you’re out shopping for the best aquarium sand for your fish tank.
Sand Type
First, choose the sand for your sand aquarium. Live and dry sands are usually available. is freshwater-packed sand with beneficial bacteria and microorganisms? Before adding live sand to your aquarium, don’t rinse it. This bacteria-colonized sand allows fish to be added immediately. This sand is perfect for freshwater aquariums but also works well in planted tanks.
However, dry sands are shipped without bacteria. Cycle your fish tank to grow bacteria in dry sand. The only problem is that this might take a few days or even weeks, so dry sand may not be the ideal choice if you want to have your aquarium up and running immediately after adding the sand. Saltwater aquariums are like dry sands. Examples include aragonite substrates.
Other types of sand for aquariums include play sand, which comes in varying grain sizes and colors to give your aquarium the most natural look. Blasting sand is polished yet looks like play sand. Silica pool sand, used for swimming pools, makes a great aquarium substrate.
Grain Size
Sand particle size is also crucial. Sand grains are typically 0.1–2 mm in diameter. Large-grain sands provide greater aeration but less protection and more debris. They house burrowing animals. However, smaller grains can compact and become anaerobic, preventing detritus. To keep your fish safe and healthy, the ideal aquarium sand should include medium-sized granules.
Sand quantity
- Your aquarium’s sand needs depend on its size, shape, and grain size. Fine sand takes up less space than coarse for a given weight.
- For a 1-inch sand layer in your aquarium, you may need one pound per gallon. Thus, a 20-gallon tank requires 20 pounds of sand.
Sand hue
- Sand hues vary. Your aquarium’s appearance depends on its sand hue. Thus, choose white or black sand to enhance your tank’s appearance.
Cleanability and Maintenance
- Some sand aquariums are hard to clean while others are easy. Larger grains enable garbage and uneaten food to sink to the bottom, but a suction-based sand cleaner may readily remove it.
- Finer sands gather waste and grime on top, making cleaning easier. However, species that sift sand to find food may deposit waste and dirt at the bottom, making cleaning difficult.
- Bacteria-laden sand is low-maintenance. Your aquarium will stay clean since the bacteria digest fish waste and uneaten food at the bottom.
