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. Pacifica is a fine-grain natural aquarium sand blending rich red hues with darker sands ranging from gray to black. It adds rich warmth and contrast to canyon-style aquascapes when paired with sandstone, petrified wood, or light-colored hardscape. Measuring 0.4mm to 0.9mm, this smooth sand provides a safe sifting surface for Corydoras, loaches, and dwarf shrimp without causing impaction, while creating bold visual contrast against bright green aquatic plants.

Key Features & Benefits

  • Fine 0.4mm to 0.9mm granule sizing creates a fine bed ideal for foreground beaches and detail pathways.

Reviews

Beautiful red

"Love the contrast in the tank. I did not expect it to be as beautiful as it turned out. The reddish dark brown mixed in with the lava stone makes it pop! 10/10 will buy again."

— Daniel J. (5/5)

Looks great and is heavy

"Looks great and is heavy enough that it doesn't kick up and stay suspended in water column when used with bigger bottom dwelling fish."

Substrate looks great.

"Substrate looks great."

— Daniel H. (5/5)

"Great substrate. Cleared up after just a couple of rinses. It's not quite as red as the pictures make it look, being much more black, but it still looks great."

— Mason (5/5)

Great color!

"Great color!"

— Brett D. (5/5)

Beautiful sand but damaged in shipping

"This sand is beautiful, sadly it wasn’t packaged well and fedex delivered the bag punctured so a lot had leaked out. I am still giving 5 stars because I sent photos of the damaged package and Buceplants made it right. It was pretty dusty and requires a good washing, it is very fine as advertised."

— Holly K. (5/5)
