Ultum Nature Systems Controsand is a line of decorative sand substrates designed for use in planted aquariums and aquascaping. Sequoia Controsand is a mixed pebble gravel with varying granule size. The color palette includes a blend of warm and cool tones, making it a good all-purpose gravel for planted aquariums and terrariums. Its larger average granule size makes it great for larger aquariums and plants with robust root systems. Like other Controsand substrates, Sequoia will compliment vibrantly colored aquatic plants and livestock.
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.
Controsand is available in two different granule sizes and four different colors to accommodate design preferences and various styles of aquascaping.

"Nice mix of rocks for a river bed style tank."
"Bigger stones than anticipated but my shrimps don't seem to mind. Adds a nice bit of contrast in my tank without lightening it too much. Will order again!"
"This substrate looks great. Its bigger size is a nice contrast to the typical size of gravel and is still small enough for good coverage. The color variety is nice and gives a realistic look for my tank that most stone can’t get quite right."
"Definite pebbles texture. More on the grayish neutral tone. Looks great with elephant stone."
"Stones are much larger than expected. Was hoping for more of a scatter gravel for detailing a new AquaScape."
"Wonderful product. The quality was as expected from UNS. Expect lots of dust but once you rinse it off the color variety in the bag is spectacular. I set it on top of UNS Black Controsoil and it adds a nice contrast."
"Like with most gravel it needs a good rinse when opened but shipping was super quick and I can’t wait to get it in some tanks!"
"Exactly what I expected and I recieved it sooner than expected. It took 4 days to arrive."
"Beautiful natural pastel colored detail larger gravel. Make sure to give them a good rinse as it is very dusty. Looks great when paired with controsand bora."
"Really pretty rocks that come in various natural colors and different shapes"
