UNS Controsoil Black

UNS Controsoil Black is a quality planted aquarium substrate designed to provide a foundation for healthy plant growth while maintaining stable water conditions for freshwater inhabitants.

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.

Benefits:

  • 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

DATA ANALYSIS
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.

Volume and Tank Size Recommendation
3 Liter - 9 Gallon (34 liters) Tank: (Ultum Nature Systems 45U Standard Tank

10 Liter - 20 Gallon Tank (75 liters) Tank: Ultum Nature Systems 60U Standard Tank

Controsoil is available in various granule sizes and colors to accommodate user preference and aquatic plant choice.

FINE - Ideal for shorter root aquatic plants such as foreground plants
NORMAL - The standard for larger scale aquariums and aquatic plants with thicker root

Great fit, truly doesn’t slide off heel
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium, Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
I’ve scoured all the lands looking for a no-show sock that was 1) thin, 2) quality, soft, breathable material, 3) didn’t dig into my feet/heels, 4) doesn’t shrink, and most importantly 5) stays on the back of my heel without a bulky non-slip rubber piece and these check all the boxes! Perfect for low profile women’s work shoes like Keds, etc. Not low enough for most flats though. I wear a women’s size 9.

So good - I’m buying MORE.
Number of Items: 3, Color: White (3-pairs), Size: Medium
I’m gonna give you more detail than you need about why I’m buying these socks again. I’ve been the mom of girl athletes. I’ve been a model and a fashion director. I’ve worn every brand of shoe on the planet and never found a shoe that did NOT find a vulnerable spot on my foot to rub raw. Even my beloved white Jack Purcell sneakers. With that said - I don’t like socks. I’ve bought a TON of them in 35+ years.....all major brands. They shift. They lose their shape. They get holes in them and wear out too fast. Not these. I retired this year, and knowing I’d be in sneakers a lot, traveling, sightseeing ...... I bought these 6 months ago and have worn them constantly. I’ve traveled with them. I’ve washed them in hot water and bleach. The socks are like brand new. They are exactly the right cut so as not to be seen in a basic sneaker. The little silicone patch on the heel stays put. Not once have I had to dig down into my shoe and pull the sock back up. The socks have stayed soft and EXACTLY the same as the day they were new. Like I said - I am back to buy them again. Great quality!

Stay put!
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
Nice and thin, soft, and stay put. I wear an 8 shoe and don’t like a thick sock taking up room. These socks are a bit tight on big toe. Wish they came in large.

The best
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
The best no show socks I have found. Stay in place very well and hold up wash after wash. I have tossed all the other brands I’ve bought over the years and stocked up on these as I was tired of digging through the drawer hoping to find a clean pair.
