## Overview

Reef Flux by Reef HD is a premium fluconazole-based aquarium treatment designed to combat fungal infections and stubborn bryopsis algae in reef tanks. Lab-tested for purity and free from fillers, it supports coral health and reduces algae buildup on equipment, making it a must-have for serious reef keepers aiming for a pristine, colorful aquatic environment.

## 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: This works!
Review: For years, I had battled what I thought was green hair algae. Tried every trick in the book to cure GHA, and nothing worked. It was a plague that took over one of my tanks so bad that I shut it down. I saved one piece from that tank, and put it in my other 10 year mature system, and the plague took over that system. The constant pulling of algae almost drove me completely out. I finally came across an article that explained the difference between GHA and Bryopsis, and found that other aquarists had had success in eliminating with fluconazole. I’m almost two weeks into treatment, and it’s mostly gone, and I’m seeing less of it every day. I was cleaning clumps of it off my powerheads on an almost daily basis. My powerheads have stayed completely clean since the first day I used the treatment. It also seems as if my corals are much happier and colorful, and it seems that the coraline algae growth has accelerated. Those algae plugged powerheads that needed cleaning every week are now turning purple. I’m using GFO while doing the treatment, so I’m not seeing any nutrient spikes. Really happy with it so far.

## 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

*by C***A on 29 October 2024*

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!!
