About Bulk Reef Supply
Bulk Reef Supply sells saltwater reef and freshwater aquarium gear, from RO/DI systems, lighting and pumps to additives, live fish and corals.
Its Black Friday Event is on now, running Nov 1 to Dec 1, 2026, and economy shipping turns free over $49 within the 48 contiguous states.
Bulk Reef Supply was founded in Minnesota in 2007 by Ryan Batcheller and Andrew Duneman, two friends looking for a business of their own. Ryan, a reef hobbyist, wanted a simpler way to feed his corals than mixing many foods, and the answer became BRS Reef Chili Coral Food. Own-brand additives, filtration media and reverse osmosis/deionization systems followed, and the company now operates from Golden Valley, Minnesota, as part of Aperture Pet & Life.
Freshwater keepers have a dedicated BRS division, and a wholesale branch serves local fish stores and other aquarium businesses. Education is a big part of the operation, with BRStv videos, written articles, reef calculators and live shows alongside the catalog. The company says its customer care team is made up of hobbyists and that it stocks only products its own aquarists use.

How to use a Bulk Reef Supply coupon
- Codes go in the promo code field, either in the Bulk Reef Supply shopping cart or at checkout.
- Each code works once per customer, covers in-stock items only and won't combine with another offer.
- MAP-priced products and gift cards sit outside promotions, so a code won't touch a MAP-priced light and can't buy an eGift card.
- The 5% off for military, teachers, nurses and first responders runs through BRS's own form rather than a third-party service, so sort that out before the order you want it on.
If your Bulk Reef Supply code doesn't work
- Minimum order: "5% Off Sitewide" needs an order of at least $50; "$25 Off $200 with Brs App" needs an order of at least $200.
- Exclusions: MAP-priced products and gift cards are excluded from promotions; clearance items are final sale.
- Combining offers: Coupon codes can't be combined with other offers, are one use per customer, in-stock items only, and expire.
- Where to enter it: Codes go in the promo code field in the shopping cart or at checkout.
