Delivered in 10 pure capsules, it treats up to 100 gallons without fillers or additives, ensuring safe use in mixed reef tanks while maintaining coral and fish health. ## Description Reef Flux is a fluconazole treatment that is effective against certain fungal fish infections. It contains no fillers or additives and is lab tested for purity. A notable side-effect of fluconazole is that it is extremely detrimental to bryopsis algae. Previously known as Algae Buster, Reef Flux is an aquarium fluconazole treatment that is effective against fungal fish infections. To avoid unintended nutrient spikes it should not be used in tanks with refugiums that have Caulerpa and Bryopsis. Review: 4X dose (against recommendations of supplier) got rid of all my bubble algae in my fully stocked mixed reef tank. So happy I don’t have to deal with it anymore. No harm to corals or fish. However, it did kill all my coral line algae as well so just know that this stuff will kill any algae including the good stuff, it does not discriminate. Use at your own discretion, results may vary!!! Review: I had an explosion of green string algae and red bacteria slime!! My neighbors were selling there little tank so i bought it. Long story short I inherited issue, after issues!! Ugh! I was so frustrated! I researched everything I could find online and went to fish stores asking for advice. I ended buying this and now my tank is free and clear of all the yucky algae!!! First picture is the after picture and the others are the before. I didn’t take any good before bc my tank was embarrassing. 😩 also my tank is a 20gal but I only used one capsule for it because I have the live rock that takes up volume in the tank.. I rather under dose then over. One capsule worked! Also, if your having a aiptasia problem get some Berghia Nudibranch!!!! I bought 4 for mug little tank and I thought they died or something after like a month but then all of a sudden about a month and a half later I see tones of them in my tank. They are every single aiprasia and believe me I had a LOT! Took about 3 months to clean them out. But they’re gone!!! Yay!! ## Features - Item Category: Aquarium Pond Water Treatment - Item Trademark: Reef HD - manufacturer: Reef HD ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B078SYK9N2 | | Best Sellers Rank | #39,998 in Pet Supplies ( See Top 100 in Pet Supplies ) #292 in Fish Medication & Health Supplies | | Brand Name | Reef HD | | Customer Reviews | 4.3 4.3 out of 5 stars (1,061) | | Item Form | Capsules | | Item Weight | 0.63 Ounces | | Liquid Volume | 100 Gallons | | Manufacturer | Reef HD | | Target Species | Fish | | UPC | 867038000415 | ## Product Details - **Brand:** Reef HD - **Item form:** Capsules - **Item weight:** 0.63 Ounces - **Liquid volume:** 100 Gallons - **Manufacturer:** Reef HD ## Images ![Reef HD - Reef Flux 10 capsules - Image 1](https://m.media-amazon.com/images/I/61RF61s7E8L.jpg) ## Questions & Answers **Q: Is this 100% fluconazole? No other Ingredients.** A: I would like confirmation of this question also. According to everything I can find it is only 200mg of Fluconazole, but nowhere from ReefHD. Are additional ingredients not required to be disclosed on the label? **Q: How many milligrams is each capsule?** A: Should be 200mg. It doesn't say on the bottle, but 1 capsule treats 10 gallons and you need 20mg per gallon. **Q: Is it normal to see no results in 8 days with green hair algae and bubble algae?** A: I've only ever used this for Bryopsis, so it may be different for bubble and hair algae. But it did take quite a while to go into effect for the Bryopsis. 8 days was not enough to see any change. It took closer to 14 days to see any reduction. **Q: I have a 40gal. So, two doses here. Should I dose once per week or once every two weeks?** A: I believe only the one time then add airstone for extra oxygen do a water change as directed on the bottle ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by R***N on 16 February 2026* 4X dose (against recommendations of supplier) got rid of all my bubble algae in my fully stocked mixed reef tank.

I opened the capsules, mixed the powder with saltwater, and added it to the aquarium water as instructed. Within 12 hours (overnight) serious problems started. Fish went into severe stress/shock Snails were lost Oxygen levels dropped rapidly To prevent a full crash, I had to: Add emergency oxygen/aeration Turn the skimmer back on Perform a 20% water change At this point, 36 hours after dosing, I still don’t know if all fish will survive. There was no clear warning in the instructions about: Dangerous oxygen depletion High risk to snails The need for emergency aeration The possibility of needing immediate water changes This product may kill algae, but in large systems it can create a serious and sudden oxygen crisis. This review is written 36 hours after use, during active damage control. I will not use this product again ## Frequently Bought Together - ReefHD Reef Flux Anti-Fungal Treatment (100 gal) - Chemi-Clean - 2 g - Seachem PhosGuard, 100 mL bagged - 67101850 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pe/products/314353228-reef-hd-reef-flux-10-capsules](https://www.desertcart.pe/products/314353228-reef-hd-reef-flux-10-capsules) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-04-22*
