Ultum Nature Systems Controsand is a line of decorative sand substrates designed for use in planted aquariums and aquascaping. Vesuvius Controsand is a chunky gravel made from Black Lava Rock. Its porous surface supports a healthy ecosystem while its inert composition is ideal for freshwater aquariums. The substrate is versatile and can be used as a standalone choice or in combination with your favorite cosmetic sand. Vesuvius Controsand would work particularly well in shrimp tanks!
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.

"8L bag is a perfect amount for my 20 gallon long tank setup for shrimp"
"I’ll buy it over and over!"
"Quick shipping good customer service"
"So far as ive been using for my tank, and now my 3rd it has done the job well, providing good nutrition but not overwhelming the tank itself."
"I’m a newbie so don’t have anything to compare it to, but it was a good amount for my 10 gal tank and I have no complaints!"
"Love the crushed lava rock in my tank! And I got the package pretty quick!"
"If you like Kona, you may like this even better"
"Every thing arrived on time and was more than enough for what you think it is!! Will definitely order again!!!"
"Only got this because Kona wasn’t available but, good quality, had to rinse quite a bit but otherwise it’s amazing"
"Thought this would be the perfect substrate for an old school UGF shrimp tank. Should provide plenty of biological filtration due to its pores nature and the added UGF. Looks better than pictured with shades of dark brown/black with other lighter shades of brown mixed in."
