Product Overview

Ultum Nature Systems Controsand offers a versatile lineup of natural decorative sands and gravels designed to give any planted tank or freshwater aquarium a finished, professional look. Maui is a black cosmetic sand in cool-toned hues that make lighter driftwood, pale stone, and vibrant green plants pop, while letting colorful dwarf shrimp and bottom dwellers steal the spotlight. In addition, its coloration makes it a good pick for separating planted zones from open display areas or used with lighter aquarium gravel or sands to create clean pathways.

Key Features & Benefits

  • Fine 0.4mm to 0.9mm granule sizing creates a uniform black substrate bed ideal for foreground pathways and dark layouts.
  • Cool dark palette brings out maximum visual vibrancy in colorful shrimp, bottom-dwelling fish, and bright aquatic foliage.
  • Natural decorative geological composition safe for aquariums, terrariums, and creative paludarium displays.

Usage & Application Guidelines

  • Distribute the granules evenly across foreground areas, dark pathways, or dedicated detail zones.
  • Pour water gently over a plate or plastic barrier during filling to avoid disturbing your hardscape arrangement.
  • Pair with root tabs or layer over aquarium soil when planting heavy root-feeding species in sand zones.
  • Note that Maui sand contains natural minerals that may slightly increase water hardness parameters.

Great products!

"Excellent product! I love the color and texture of both of these. Very happy with my purchase."

— Thomas C. (5/5)

Great color that makes the tank pop

"I recently purchased this aquarium sand for my tank and I am really impressed with how it looks in my tank. It gives the tank a really clean look. Also, the grain size is just right."

— Clark C. (5/5)

Best of the best

"Top notch quality substrate. Looks absolutely amazing in my tank"

— Andreas F. (5/5)

Good black sand, nice and dark!

"The sand is very nice and already very clean. Only washed it once. It looks excellent underwater, very black like I wanted and makes my plants and rocks pop against it. It’s a consistent color too, there’s a little variation but it’s subtle. The 3L bag was more than enough for my UNS 30T, my only concern will be how much this sand will raise my water hardness over time, but a water change can fix that if it gets too crazy."

— Chris M. (5/5)

Perfect

"Exactly what I wanted and only took 10 ish minutes of rinsing to clean"

— Emmery S. (5/5)

Crushed hard scape, missing items

"Much of my hardscape arrived crushed and damaged, and the controsand I ordered never arrived at all. I received a refund for the sand but for what I received, I’m fairly disappointed. The wood was very small and mostly broken up. Not what I was hoping for."

— Alfonso S. (2/5)

Fine sand

"Great size granules as an accent sand that is different from typical beach style sand."

— Christopher S. (5/5)
