Overview
The large surface area is approximately 2.9 million m2/m3 or 2900 m2/liter due to the microscopic pore size of about 2 nm (nanometers). Indo feather rock and white pumice also have microscopic pore sizes but are still many times larger than Neo filter material. However, they offer many advantages in terms of cost and pricing.
API gear is commonly used for freshwater planted tanks, nano aquascapes, and routine maintenance — always match capacity to your tank volume and livestock.
