UNS Controsoil is an aquarium soil from Japan made of high quality natural soil and volcanic ash. Proper substrate is vital for any successful aquarium, not only for the plants to flourish but also to buffer the water to optimum levels for certain fish and shrimp. Controsoil will keep the pH of alkaline water below 7 which is ideal for keeping Caridina shrimp and most tropical fish.
With other soil, it is common to experience algae issues during the initial month or two of a new set up. This, “new tank syndrome” is characterized by brown or green algae on the glass, plants and hard scape as well as cloudy or smelly water. This is caused by high levels of ammonia (NH3) which many soil manufacturers add into their products. Although the ammonia will help cycle the tank, too much can cause problems so it is necessary for users to do daily water changes during the first few weeks of use. Controsoil is the perfect solution for those who want good plant growth without the headache of excessive ammonia. Many users have reported success with using Controsoil and adding shrimp or fish within 24 hours of a new set up, but we always recommend cycling the tank first and making sure ammonia and nitrites are at 0.
How much soil do I need?
Length x Width x Desired Substrate Height (in inches)
Divided by 60
= Liters of soil needed
Normal Granules ~ 5mm
Good for larger tanks (20 gallons or above) with larger plants.
Fine Granules ~ 3mm
Perfect for smaller tanks (Less than 20 Gallons), or to use as a top coat to place on top of medium granules. Finer soil granules help small plant roots to anchor into the substrate easier and keep from floating.
Extra Fine Granules ~ 1mm
Perfect for smaller tanks (Less than 20 Gallons), or to use as a top coat to place on top of medium and fine granules. Finer soil granules help small plant roots to anchor into the substrate easier and keep from floating.

Bought a 10L bag of each size and couldn't be happier, no dust at all, and makes the aquaeium look clean.. Bangs with alot of red plants.. And as usual lightning speed shipping, and packaged to handle a 2500 mile trip with no damage.. Picked up a 40 gallon cube to do it all over again.. Thanks Buce!
Great substrate for the aquarium. Wasn't that dusty as other substrates, TBH I really didn't notice any extra particles from the soil the next day. Great choice.
Got two 3 liter bags for my UNS 45u tank.
Holds plants very well. 100% pleased. No rinsing necessary. No cloudiness whatsoever.
Bought 10L of the extra fine for the UNS 45U. Probably have about 25% of the bag left after laying down about 2 inches of substrate. Water cleared up quickly. No issues planting stem plants or carpet plants.
Under Twinstar lighting (E series) the black substrate looks a bit warmer and lighter in color to me. Almost like kidney bean color but I don't mind.
My plants seem to really be enjoying this stuff. So is my elephant nose fish, because it's very soft and fun for him to dig through. It will drop your pH though. Mine went from 7.4 to 6.4. If you have freshwater snails, you may want add calcium to your tank keep their shells hard. Lower PH weakens the shell.
