Description

Ultum Nature Systems has partnered with Marfied to bring you Ultum Nature Controsoil. UNS Controsoil is an andisol based substrate created from the volcanic ash of Mount Aso in Japan. Choosing the right substrate is a vital component for a successful planted aquarium. It allows plants to flourish while buffering the water to optimum levels for certain freshwater livestock. Proper aquarium substrate is paramount to successfully growing healthy aquatic plants. Controsoil absorbs impurities in your water column to provide a healthy environment for livestock. The texture and porosity provide the perfect medium for plant roots to latch onto. This soil is specifically designed for planted aquariums and shrimp keeping without excessive ammonia, which can lead to algae during initial use. Ultum Nature Controsoil does not require any rinsing and won't cloud your water when properly used. For the best results, place your Controsoil into your aquarium prior to adding water. Add water slowly without stirring up the soil For planted tanks, we recommend using UNS Controsoil with UNS Plant Food fertilizers. Directions: Place the substrate in to an empty aquarium. When filling the aquarium with water, place a dish or other item to disburse the water flow and minimize disruption to the substrate layer. How much soil do I need? Length x Width x Desired Substrate Height (in inches), Divided by 60 = Liters of soil needed. Made in Japan. Available in 2 colors: Black and Brown. Available in three granule sizes: Normal (5mm), Fine (3mm), and Extra Fine (1mm). Available in three bag sizes: 1L, 3L, and 10L.

  • Great Substrate for Planted Aquariums
Size: 3 Liters (2.7 kg) Color: Black - Extra Fine
This is great substrate for planted aquariums. I love that it is low ammonia because beneficial bacteria don’t need a lot to ramp up. I combine this with the APT S Starter Bacteria underneath and it cycles the tank in two to three weeks without fail. The small ammonia release from this substrate is perfect for the bacteria and results in zero ammonia and zero nitrite with low nitrate in a very short period of time. This isn’t nutrient rich like Amazonia but you can crush up root tabs and sprinkle them on top of the APT S before you pour in the Contrasoil for a boost. I usually do this and dark start the aquarium per the APT S instructions and the results are great. Low algae and great plant growth. Because this is partially made from volcanic ash it really soaks up things and keeps your tank clean as well. It’s strange but it does absorb a lot of impurities like advertised. This soil with Purigen makes a crystal clear aquarium. It’s definitely best for clarity. All in all, a great product. Thanks UNS! ... show more

  • Quality substrate at a perfect size
Size: 3 Liters (2.7 kg) Color: Black - Extra Fine
The dip-n-dots large sized substrate balls weren’t ever my favorite. Opting for a slightly more natural looking finer substrate, this one is perfect although a little pricey. But to be expected from the UNS brand; you get what you pay for: quality! Would use for my next scape build for sure.

  • Did what it's supposed to
Size: 10 Liters (9.1 kg) Color: Black - Extra Fine
The media could not be loaded. Didn't need to prewash grew my plants quickly and my tank has had perfect ph levels and no new tank syndrome! It is expensive but it's less expensive than buying a fluval first and having to start new once your tank turns green and mushy

  • Good substrate for a planted aquarium for non digging fish
Size: 10 Liters (9.1 kg) Color: Black - Extra Fine
It is a fine quality substrate but you have to follow the directions. No mixing with other substrates which will make it mud up your tank. Also very important that you do not use with any fish that like to dig, which will also mud up your tank water. I am specifically using for potted terra cotta aquarium plants & as long as you put a good layer of gravel substrate on top of each pot it does a wonderful job, very good media for growing plants. I cant use it as I intended as I have the digging Blood Parrot cichlids. ... show more
