Ultum Nature Systems Controsand is a line of decorative sand substrates designed for use in planted aquariums and aquascaping. Maui Controsand is a fine-grain natural sand. Its cool-toned palette works well when paired with natural stone and provides subtle contrast.
Whether you're setting up your first aquascape, or you've been in the hobby for years, Controsand is easy to use. Just rinse the substrate gently to remove finer grains, then spread it evenly in your aquarium for a naturally earthy tone.

"Excellent product! I love the color and texture of both of these. Very happy with my purchase."
"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."
"Top notch quality substrate. Looks absolutely amazing in my tank"
"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."
"My grandson hobby & school projects."
"First time using this substrate and I love it! Looks great, my plants are doing well in it and I will absolutely continue to use it for any new tanks I do!"
"Love this stuff! It’s so nice and shipping was fast."
"Exactly what I wanted and only took 10 ish minutes of rinsing to clean"
"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."
"Great size granules as an accent sand that is different from typical beach style sand."
