Ultum Nature Systems Controsoil is an aquarium soil from Japan made of high-quality natural soil and volcanic ash.  Choosing a proper substrate is vital for any successful planted aquarium.  This is not only for aquarium plants fo flourish but also to buffer the water to optimum levels for certain fish and shrimp.

Controsoil by UNS will keep the pH of alkaline water below 7 which is ideal for keeping Caridinia shrimp and most tropical fish.

When compared to alternative aquarium soil, it is common to experience algae spike during the initial month or two of a new set up.  This is commonly referred to as "new tank syndrome" and is characterized by brown or green algae on the glass, aquatic plants, and hardscape along with cloudy or smelly water.

Specifications:

Normal Granules - 5mm

Good for larger tanks (20 gallons or above) with larger plants.

Fine Granules - 3mm

Perfect for smaller planted tanks (less than 20 gallons).  Controsoil can also be used as a top coat and placed on top of medium granules.  Finer soil granules help small root plants, such as Hemianthus Callitrichoides, to anchor into the substrate easier.  This also help prevent pesky floating upon filling the tanks.

Extra Fine Granules - 1mm

Perfect for small planted tanks (Less than 20 gallons), or to use as a topcoat to place on top of medium and fine granules.  Finer soil granules help small root plants, such as Heminathus Callitrichoides, to anchor into the substrate easier.  this also help prevent pesky floating upon filling the tank.
