ReefHD Reef Flux


The most effective nuisance algae treatment in the hobby! 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 Bryopsis or Caulerpa refugiums.

Directions: Turn off skimmer for first 3 days. Activated carbon and phosphate remover can be used after 3 days, but remove other chemical filtration. Empty 1 capsule for every 10 gallons of tank water (20mg per gallon) into high flow area in sump. After 14 days perform a minimum 30% water change. Do not overdose. Filter socks are recommended during treatment in order to help clean the aquarium.

Only for use on ornamental aquariums and fish. Not for human use and not for treating fish intended for human consumption. Keep away from children and animals. In case of accidental overdose, contact a health professional immediately. In case of accidental tank overdose, the medication can be removed using Purigen.


Frequently asked questions:

What happened to Algae Buster?

Algae Buster was relabeled due to being so effective that it fell into a loophole where it would have been classified as a pesticide which are extremely expensive to register. Reef Flux is the same fluconazole product with a different label. A filter sock is recommended if using Reef Flux in tanks that contain Bryopsis and Caulerpa.


What is Reef Flux and how does it work?

Reef Flux is a fluconazole-based reef treatment for topical and systemic fungal fish diseases.


Will Reef Flux harm my saltwater fish or invertebrates?

Reef Flux is reef safe for fish and invertebrates as long as it is dosed correctly.


Can Reef Flux affect my nitrates and phosphates?

It is possible that Reef Flux can raise nutrients as it treats your tank, especially if there is a Bryopsis or Caulerpa refugium. This is why it is a good reason to use filter socks while treating fungal fish infections with Reef Flux.


Does this seem like a lot of packaging for 10 capsules?

We received feedback from stores while developing Reef Flux, and many had shoplifting concerns with smaller packaging sizes. Another issue is that for legal reasons there is necessary information on the label that needs to be legible. As a result the packaging size was adjusted to fix any concerns.

A Little About Our Livestock Pictures

Our pictures are taken under the Zetlight ZP3600 LED. We try to post two pictures of each coral to give you a better idea to how it may look in your tank. We take one picture with all the leds at full power and one picture with just the blue and violet leds at full power. We can't guarantee an exact color match. So many factors, monitor settings, your eyes, and types of lighting affect color, so it is impossible for us to guarantee an exact color match. Our pictures are shot to represent the items as they appear to us in our photo tank. Please see our Lighting example here.
