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.
