Nisso Custom Soil is one of the original nutrient soil for aquariums made in Japan.
Nisso Custom Soil lowers pH and has a water softening effect which is ideal for plants and shrimp. Due to the inclusion of Bentonite clay in the soil the pellets also have great functions as sponges both for absorbing excess nutrients as well as allowing beneficial bacteria to grow.
Because of this you will also find that Nisso Custom Soil does not cloud the water as readily as other nutrient soil and should be good to use immediately out of the bag.
