Bulk Reef Supply

Original BRS Products Since 2017

High-Quality Reefing Essentials, BRS Value

BRS began with a simple goal: to find a better way to feed fish and corals. From there, Reef Chili was born. That practical, problem-solving approach quickly evolved into sourcing affordable two-part dosing additives and eventually shaped the BRS product line.

Since 2017, BRS products have expanded across RO/DI, filtration, additives, foods, and maintenance essentials, helping reefers choose smarter, spend more wisely, and build better tanks.

The BRS Difference

Educational Resources

BRStv videos, helpful guides, and useful reefing calculators make it easier to choose the right products and make the best decisions for your tank.

Quality Meets Value

From sourcing pharmaceutical-grade raw materials for our two-part additives to building RO/DI systems in-house, we strive to provide the best quality products.

Support from Reefers

Get honest advice, product guidance, and help from a team that knows the saltwater aquarium hobby like the back of their hands.

BRS Warranty

Nearly all BRS brand products include a warranty of 1-year or longer. BRS RO/DI systems even include a limited lifetime warranty!
