Controsand Sequoia Gravel (3L) - Fine Sand for Planted Aquariums

In this review of Controsand Sequoia Gravel (3L) the bottom line is simple: this fine-grained substrate is best for aquarists building planted tanks or keeping bottom-dwelling species who need a soft, siftable bottom. The reviewer found the sand promotes stable rooting for plants and is pleasant to work with during set up, while requiring a quick rinse to avoid initial cloudiness. It is not a nutrient substrate, but its grain size and color make it an easy choice for aquascapes, blackwater biotopes, and shrimp tanks that rely on a natural, fine-grained bed.

Key Features

• Plant-Friendly: Designed to support healthy root growth so aquatic plants can establish and spread effectively in a planted aquarium.
• Versatile Substrate: Suitable for both large aquariums and small fish tanks, making it a flexible option for different layouts and tank sizes.
• Fine-grained Texture: The 0.4 to 0.9mm grain size creates a warm, Mojave-like tone and a soft bed ideal for delicate roots and bottom-dwelling species.
• Pristine and Ready to Use: The sand arrives clean and usable right away, though a light rinse is recommended to remove the finest particles and prevent cloudiness.
• Good for Shrimp and Bottom Dwellers: The grain size allows live shrimp and sifting fish to forage naturally without abrasive particles.

Who It's For

This substrate is aimed at hobbyists setting up planted aquariums, aquascapes, or biotope tanks that prefer a fine-grained, natural-looking bottom layer. It suits owners of bottom-dwelling fish and live shrimp who need a soft substrate to sift and root without sharp edges. The sand also pairs well with Dragon Stone and driftwood in blackwater-style builds.

Those looking for a nutrient-rich planting medium or heavy mineral content should look elsewhere or use this sand over a root tab system, because Controsand Sequoia is a neutral, decorative substrate rather than a fertilizer substrate.

Pros & Cons

Frequently Asked Questions

Do I need to rinse this sand before adding water?
Yes, a light rinse is recommended to remove the finest grains and prevent initial cloudiness when the tank is filled.

Is this substrate good for live shrimp?
Yes, the 0.4 to 0.9mm grain size is well suited to live shrimp and other bottom-dwelling species that sift the substrate.

Can I plant directly into this sand?
You can plant into this sand, but for heavy root-feeders consider adding root tabs or a nutrient layer underneath since this is not a fertilizing substrate.
