ReefHD Reef Flux Anti-Fungal Treatment (100 gal)

This is strong medication for your aquarium, be careful. I was getting algae pretty bad, and filters and pumps were running pretty strong to clean my nutrients without slowing it down. Reef flux will destroy GHA but some corals will not be happy and introverts will eventually die off as did in my case unfortunately. I wouldn't use this again if I had snails but it's a last option time of thing.

I struggled with a couple of tufts of hair algae in my reef aquarium for over a year. Despite all my efforts, I couldn’t eradicate it. I decided to try ReefHD Reef Flux. After 3 days of the initial treatment, all the algae disappeared overnight. My fish, corals, and invertebrates all seem to be fine. This stuff is amazing and I highly recommend it. Follow the directions and be patient, it really does work.

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

I have been reefing for over 30 years and I never had to deal with Bryopsis until now 8/1/2026 so I just wanted to let people know that although we don’t like to try meds for out reef 🪸 because they never work or end up killing our coral this stuff really works. I manually removed as much as I could and I dosed 50% of the recommended dose on my 100 gallon so 5 pills 💊.. I waited two days and dosed the other 5 pills 💊 and within a day or two my bryopsis was all gone nothing was left it detached from all my rocks , corals and even snails 🐌.. it works it really does so if you use it hopefully you have the same experience I did with it 👍👍

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!!

The product works well but in the description it says it's a liquid and it's not. It's capsules that you have to either try to pull apart or cut the tip off to get the powder out.

This stuff works like a dream. I have a 120 gal that’s been up now for 1 1/2 years. I was plagued by green hair algae and bryopsis much of that time. You must follow the directions. FULLY dissolve the tablets. For me this meant I emptied 3 capsules at a time into a quart of tank water over about 10 minutes for each of the 3 capsules. Don’t rush it. I also did water changes during the 3 week period and added the correct amount for the water change performed. I.e. if I changed 10 gal I added 1 capsule. I took my skimmer off line for 3 days and no carbon for 3 weeks. Ran GFO and filter socks as suggested. As expected my PO4 and NO3 went up (doubled PO4 - 1.4 and NO3 - >5) since they were no longer tied up in the GHA. I also believe that the GHA dying adds to both. I did my 30% H2O change after the 3rd week started carbon and changed GFO. I soaked all powerheads and pumps in vinegar and warm water and thoroughly cleaned. I saw no detrimental affect to any livestock and since my coraline algae has started to explode because the GHA isn’t occupying that Realestate. 😁 I had no issues with Dynos or Cyanos. I do run a 50W Pentair UV tuned for those blooms. After months of trying to manually remove and fight a losing battle I considered a tear down and Hydrogen Peroxide nuclear option. Now I’m kicking myself for not trying this sooner. I’ve been in this both professionally and as a hobbyist for over 30 years and am a skeptic of miracle cures and firmly believe that patience and persistence wins out in this hobby. This lived up to the hype and I was shocked and just how well it worked. UPDATE: After 2 weeks of some elevated levels of PO4 and NO3 with normal water changes, GFO, and NOPOX dosing PO4 is .05 and NO3 is 1.47. With no GHA to bind these and the low levels, this should prevent recurring issues 🤞

Nice product

After adding this into my tank. Three anthias dead. and LPS coral polyps shrinked. Hair algea still existing.It was not good for my tank.
