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. Sequoia is the largest option in the Controsand lineup, a mixed pebble gravel with granules ranging from 6mm to 15mm, each stone looking genuinely river-worn, like it tumbled downstream for years before landing in your tank. Its blend of warm and cool earthy tones comes alive underwater, giving larger aquariums and riverbed-style layouts a level of realism that's hard to fake. Built to support robust root systems and hold its own in bigger tank dimensions, this chunky pebble gravel works beautifully as a standalone substrate, scattered along stream-style transitions, or layered with finer cosmetic sand for added depth.

Key Features & Benefits

  • Large 6mm to 15mm pebble composition delivers natural, riverbed-style realism to larger display aquariums.
  • Balanced blend of warm and cool earth tones creates striking visual contrast against colorful plants and hardscape.
  • Natural decorative geological composition designed for aquarium, paludarium, and other terrestrial use.
  • Safe, rounded pebble shape allows bottom dwellers and dwarf shrimp to forage without risk of impaction.

Usage & Application Guidelines

  • Rinse the gravel gently with clean tap water before installation to clear fine dust particles from transit.
  • Distribute the granules evenly across foreground areas, hardscape borders, or dedicated accent 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 anchoring plants with robust root systems in pebble gravel zones.

Frequently Asked Questions

1. Do I need to rinse this aquarium substrate before adding it to my tank?

Yes, giving Controsand Sequoia a quick rinse in clean tap water before placing it in your aquarium is recommended to remove loose dust from transit and ensure immediate water clarity.

2. How much substrate do I need for my aquarium size?

For foreground pathways or focal accenting, a single 3-liter bag covers most tanks up to 9 gallons. For full bed coverage or larger setups up to 20 gallons, an 8-liter bag provides plenty of volume to build depth.

3. Can I combine UNS Controsand Sequoia with aquarium sand in the same aquascape?

Yes, combining large pebble gravel with aquarium soil or fine cosmetic aquarium sand is a popular technique for high-impact aquascaping layouts. You can place aquarium soil in the rear or planting pockets for root growth and use Sequoia pebble gravel along hardscape bases or riverbed zones for striking visual contrast.

      "Nice mix of rocks for a river bed style tank."

      — Sean (5/5)

      Bigger stones than anticipated but

      "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!"

      — Thomas C. (5/5)

      Looks great!

      "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."

      — Michael O. (5/5)

      Definite pebbles texture. More on

      "Definite pebbles texture. More on the grayish neutral tone. Looks great with elephant stone."

      — Rick (2/5)

      Another Great UNS Product
