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 desertcartia 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! Review: Quality substrate at a perfect size - 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. ## Features - Designed For Planted Aquariums - Granule composition and sizes provide optimal oxygen exchange and rich nutrients for aquatic plants - Optimal For Fish And Shrimp - Suitable for all freshwater inhabitants such as tropical fish and shrimp that prefer slightly acidic aquarium water - Low Ammonia Release - Promotes and accelerates beneficial bacteria growth - No Rinsing Required - Helps clarify and detoxify cloudy water by actively absorbing impurities - pH & kH buffering - Buffers water to slightly acidic pH and lowers total water hardness for better aquatic plant nutrient consumption environment ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07C2KMW1H | | ASIN | B07C2KMW1H | | Best Sellers Rank | #15,534 in Pet Supplies ( See Top 100 in Pet Supplies ) #31 in Aquarium Substrate | | Brand Name | Ultum Nature Systems | | Customer Reviews | 4.5 4.5 out of 5 stars (121) | | Date First Available | April 4, 2017 | | Global Trade Identification Number | 00851302008566 | | Is Discontinued By Manufacturer | No | | Item Form | Granules | | Liquid Volume | 3 Liters | | Manufacturer | Marfied | | Manufacturer | Marfied | | Package Dimensions | 12.95 x 8.58 x 2.24 inches; 5.4 Pounds | | Target Species | Shrimp | | UPC | 851302008566 | | Unit Count | 1.00 Count | ## Product Details - **Brand:** Ultum Nature Systems - **Item Form:** Granules - **Liquid Volume:** 3 Liters - **Manufacturer:** Marfied - **UPC:** 851302008566 ## Images ![Ultum Nature Systems Controsoil - Freshwater Aqua Soil Substrate for Fish, Shrimp, Live Plant Propagation and Aquascaping - 6.8pH Low Ammonia, Volcanic Ash - Black, Extra Fine (3 Liter) - Image 1](https://m.media-amazon.com/images/I/71Hka6eVN9L.jpg) ![Ultum Nature Systems Controsoil - Freshwater Aqua Soil Substrate for Fish, Shrimp, Live Plant Propagation and Aquascaping - 6.8pH Low Ammonia, Volcanic Ash - Black, Extra Fine (3 Liter) - Image 2](https://m.media-amazon.com/images/I/71GSOW2U4vL.jpg) ![Ultum Nature Systems Controsoil - Freshwater Aqua Soil Substrate for Fish, Shrimp, Live Plant Propagation and Aquascaping - 6.8pH Low Ammonia, Volcanic Ash - Black, Extra Fine (3 Liter) - Image 3](https://m.media-amazon.com/images/I/81DK-L00ojL.jpg) ![Ultum Nature Systems Controsoil - Freshwater Aqua Soil Substrate for Fish, Shrimp, Live Plant Propagation and Aquascaping - 6.8pH Low Ammonia, Volcanic Ash - Black, Extra Fine (3 Liter) - Image 4](https://m.media-amazon.com/images/I/81GWF8pjiSL.jpg) ![Ultum Nature Systems Controsoil - Freshwater Aqua Soil Substrate for Fish, Shrimp, Live Plant Propagation and Aquascaping - 6.8pH Low Ammonia, Volcanic Ash - Black, Extra Fine (3 Liter) - Image 5](https://m.media-amazon.com/images/I/71f9XITn7SL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Substrate for Planted Aquariums *by S***N on February 15, 2025* 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.
