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

Beautiful sturdy, cozy chair, BUT…..
Color: White, Color: White
Updated review. I was so excited to get this chair that I jumped the gun and wrote the review prior to spending more time seated. I only have one issue, which is the back bottom of the seat cushion. That’s a big deal. It appears so thick, fluffy and inviting, however, when I sat in it for a couple of hours it completely went flat in the back feeling like I was sitting on a board. I’m 5’4” 180 lbs, which means my feet don’t touch the floor so adding a cushion will elevate me a little more. I’m OK with that but it’s going to ruin aesthetic of the chair which is which is not ok. I do love the idea of this chair. It’s design and the color. I wish the seat cushion had a zipper, which would eliminate my issue. I’d say if you’re someone who has to spend a lot of hours in this chair, you probably won’t like it. I do like the reclining back and the foot rest. It is comfortable to lay back but that doesn’t change the issue in the back bottom of the seat cushion. I absolutely love this chair, I didn’t want to get up. It’s beautiful and cozy. Assembly was easy as I’ve assembled chairs before. I changed the wheels to a double roller blade easy on hard wood floors. I also scotch guarded the entire chair. This chair is sturdy and well made.

just get it and stop second guessing
Color: White, Color: White
I reallllly love this chair. I almost talked myself out of it because of some of the bad reviews here and there but i’m glad i listened to a majority of the good reviews, because this chair is perfect. shipping: it was super fast. it came 5 days earlier than expected. I got it on a Monday when it said it’d be here on Friday packaging: double boxed and bubble wrapped. Didn’t find any dings or scratches on anything. all parts were there including instructions assembly: my boyfriend put it together in 40 minutes. We didn’t have any issues zipping up the back cover like other reviews said and he said it was easy instructions to follow, and easy to put together. size and comfort: it’s bigger than the pictures let on! I’m 5’3 135lbs and feel like I’m sitting on a giant cloud. The comfort is 10/10. I just had a chair with basicslly zero butt cushion which i cannot have while working from home 8+ hrs a day in a chair. Comfort was the most important for me and I finally can’t feel the flat seat under me. I can’t express how comfy it is. Functions: can move the arm rests up and down. adjust the back to tilt all the way back to a sleeping position or fully upright which i didn’t even realize was a function! The only thing with the armrests; if you’re wanting your pet on it (like advertised) when the arm rests is put down there is a big gap that isn’t comfortable for animals (as pictured) so I have to put a blanket or pillow there for my small dog to lay comfortably. I’m obsessed with the fact I can sit cross legged, normally, laying down, sprawled up, or legs up. I have room to sit however I want, and the foot rests helps a ton with feeling even more comfortable. Overall, I’d get this chair 10x over. Not only do I work from home and spend hours in a chair, but I spend additional time playing video games so a good quality chair is very important to me. This has began to help fix my posture and back and neck issues. Get it!!!

If You Sit Weird Like Me… Just Buy This Chair
Color: Galaxy Black
I work from home and spend a lot of time sitting for hobbies like Legos, PC games, and crafts—so a comfortable chair is a must. I LOVE this chair so far. I’ve always struggled to get comfortable in traditional office chairs, and the ability to move around is really important to me. With this one, I can easily cross my legs, use the footrest to stretch out with my knees bent, or just sit normally. I’m 5’4”, so my feet don’t quite touch the ground, but that doesn’t bother me since I’m constantly switching positions anyway. I’ll probably add a small pillow for extra back support and maybe fold a blanket for a bit more seat cushioning. It’s comfortable overall, but after long periods of sitting, you might start to feel it. The black sparkle version is MUCH cuter in person, and I’m so glad I went with it. A lot of reviews say, “don’t think about it, just get it”—and honestly, they’re right. I debated for a couple weeks before buying, and I have zero regrets. Assembly was easier than I expected. I tend to get frustrated putting things together, but this was pretty painless. One tip: check inside the cushioned back piece for the extra headrest part—you’ll need it to attach to the hard back before inserting it into the cushion. Once I figured that out, the rest was simple. The chair is a bit larger than a standard office chair and can feel a little bulky depending on your desk setup, but I actually like the extra space since I move around a lot while sitting. It feels sturdy and well-made. It’s also slightly warmer than a mesh chair, which I personally love because I’m always cold. I am just happy to find a chair that feels comfortable like a recliner and movable like an office chair.

Great chair
Color: Pink
I love this chair! I use it for streaming and working on making jewelry! It’s very comfortable and I love that I can sit different ways in it! I can stream longer than I could in other computer chairs I’ve had! I definitely recommend this if you have to sit for a long time but like to sit in different positions! The instructions were a bit confusing but I did figure it out! I have had to spot clean it a few times because of kids and pets but the material has held up! The back is very comfortable and supportive! I like that I can adjust it! Great chair for the price! It’s held up well and I like that you can adjust the back!

Good office chair for the money
Color: White
It is a good quality chair that is comfortable and aesthetically pleasing. The arms aren't necessarily big enough to hold our cat - but that's because he's fairly large by cat standards. The arm rests moving is definitely nice and provides lots of opportunities to 'setup the chair' in a way that works best for you. The instructions were relatively easy to follow (take your time and think it through to make sure you have everything 'aligned right' at first) and the chair is sturdy and holding up well.
