Due to falling into an EPA loophole because of algaecide claims, Algae Buster has been relabeled Reef Flux, a fluconazole aquarium treatment that is effective against fungal fish diseases. Reef Flux can affect Bryopsis refugiums, so to prevent nutrient boosts you should avoid using Reef Flux in systems that have large Bryopsis or Caulerpa refugiums. You can see more details and the FAQ at reefhd.com/ReefFlux. We only sell wholesale, so if you would like to see Reef Flux in your favorite store please have them contact us. Why choose Reef Flux instead of capsules imported from India on some websites? 1. Reef Flux is inspected and lab tested to be of the highest purity. 2. Imported capsules can be expired, usually contain fillers, can contain other chemicals due to lax regulation, and be of lower quality. 3. It supports the reef economy! Reef Flux is available from R2R sponsors and retail stores, so your purchase helps build the hobby. At Reef HD we are hobbyists who spend some of our paycheck on products from other sponsors, who have employees who spend their money on other sponsors, and we all win If you have any questions we will be happy to answer them!
