A quality planted aquarium substrate provides the foundation for healthy plant growth. Ultum Nature Systems Controsoil is a natural blend of soil and volcanic ash. Setting it apart from other substrates, Controsoil does not contain high nutrient levels that can cause spikes in ammonia levels. It primarily focuses on impurity absorption and providing balance from the start. This approach makes UNS Controsoil a great choice for all skill levels and allows anyone to create a beautiful aquarium. Controsoil is available in various granule sizes and colors to accommodate user preference and aquatic plant choice. No Rinsing Required Inhibits cloudy water by actively absorbing impurities Low Ammonia Release Promotes and accelerates beneficial bacteria growth PH & KH buffering Buffers water to slightly acidic pH and lowers total water hardness for better aquatic plant nutrient consumption environment Optimal For Fish And Shrimp Suitable for all fresh water inhabitants such as tropical fish and shrimp that prefer slightly acidic aquarium water Designed For Planted Aquariums Granule composition and sizes provide optimal oxygen exchange for aquatic plants Ultum Nature Systems Controsoil along with a competing freshwater planted aquarium soil were scientifically tested in a controlled environment. The test was performed by a published, independent third party and consisted of an experiment using both soils side by side for a 2 week duration. RODI water was used and water changes were not performed for the entire duration to ensure continuity and to prevent data inaccuracy that would adversely affect final results. The below findings indicate that Ultum Nature Systems Controsoil is an ideal choice for all freshwater planted aquariums. TDS Measures the levels of combined organic and inorganic substances found in aquarium water other than pure H2O molecules. These solids consist primarily of minerals, salts and organic matter. This measurement can be used to determine the water source’s general quality and purity. Weekly water changes are encouraged to decrease TDS.   AMMONIA (NH3) AND NITRATE (NO3) Ammonia provides a jumpstart in a newly set up aquarium quickly without the use of third party chemicals and/or additional product(s). As ammonia decreases, nitrate levels increase. Once this step begins, livestock additions may be considered. This process is often referred to as “cycling a tank”. UNS Controsoil begins this process by immediately releasing minimal amounts of ammonia into the water column. Based on controlled tests performed, an aquarium may be cycled in less than 2 weeks time when using Controsoil. During the 2 week test period, ammonia levels spiked following the 6th day. This was due to the absence of water changes. Weekly water changes are always highly recommended to prevent ammonia spikes. A spike can be potentially lethal to all aquarium livestock. PH A measure of acidity and alkalinity. Controsoil successfully stabilizes pH levels to 6.8pH over time. This pH level is ideal for all tropical livestock, freshwater shrimp and aquatic plants. It is important to note that stable pH environments positively affect the longevity of a planted aquarium and its livestock.

Flourite Sand is a specially fracted stable porous clay gravel for the natural planted aquarium. Its appearance is best suited to planted aquaria, but may be used in any freshwater aquarium environment. Flourite Sand is most effective when used alone as an integral substrate bed, but it may be mixed with other gravels. Gravel modifiers such as laterite are not necessary. Flourite Sand is not chemically coated or treated and will not alter the pH of the water. Flourite Sand is good for the life of the aquarium and need not be replaced. Set-up - Although it is pre-washed, because Flourite Sand is a natural product, it may become dusty in transit and require rinsing before use to remove any residual dust. When adding water to aquarium, fill slowly to avoid disturbing Flourite Sand substrate bed. Place a bowl in the aquarium and add water directly to the bowl, allowing water to overflow softly on to the gravel bed. Initial cloudiness is normal. To remove cloudiness, use mechanical filtration (such as filter floss). Use Clarity to accelerate clearing.
