## Description

ReefHD Reef Flux 100 gal treatment size

Review: Bubble Algae Wiped Out!!! - 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: Good product - This works!

## 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 A***I on January 1, 2026*

Tank size: ~230 gallons Dosage used: 20 capsules Time since dosing: 36 hours Review: I used 20 capsules for a 230-gallon 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
