Flux Rx - 2000mg Treats up to 100Gal Reef Safe, Use on Both Bryopsis and Green Hair Algae

Best product if you have gha green hair algae in aquarium. I've used this multiple times after nitrates got out of hand and my tank was full of algae. No harm to fish or corals and algae gone in 10 days. Love this stuff I tried everything else this was a life changer.

6/30/25: Just enough for 3 big scoops and a small; will update in 10-14 days to see if it helped gha problem 7/14/25: Worked AMAZINGLY, The only thing left is Cyno. It got rid of all of my back glass GHA as well. I used it in conjunction with Microbe Special Blend Bacteria & Bioptim along with my Sea Hare.

This product is amazing. It is reef safe & works very well. The photos are about 7-9 days apart. Before & after. I used razor with it too. I’m actually shocked that the hair algae is almost gone. The only thing bad I saw was that it increases cyano. But that’s easily dealt with using slime away or whatever that product was I saw on Amazon.

Had really bad GHA and I’m typically against medicating my tank. The First few treatments didn’t work but after reading several boards I slowly upped dosage. Eventually it Cleared up my tank and didn’t affect any corals or inverts. I Highly would NOT recommend going against the dosing instructions unless you know the risks and are prepared for the worst.

Instructions say 10-14 days, started seeing a noticeable improvement in 5 with complete improvement in 8 days. No more hair algae.

I had a terrible green hair algae problem in my tank. I tried everything, including more frequent water changes, changing my light cycels, less feeding and nothing worked. I used one dose of Flux Rx and within 10 days the my tank looked amazing. NO MORE ALGAE!

Use extreme caution when using this product. While the chemical itself "may" be reef safe it will effect other parameters in your tank causing it to kill coral. I had two massive colonies of Frogspawn and Galaxy that have all nearly died off since using this product (and using Flux was the only change that had been done to the tank). While I don't think the chemical itself killed off my coral, I believe it killed something else in the tank that the corals needed to survive. Use extreme caution when using in your tank and only use it if you are sure it won't do anything to the specific corals you have.

Kill GHA in a few days in my algae tank. Safe for fishes, inverts, corals and red algaes. Not safe for weak Caulerpas, safe for healthy ones.

Eccezionale, volete eliminare le alghe filamentose in 10/14 giorni in acquario marino, sono sparite totalmente senza danneggiare pesci o coralli.

Produit efficace contre filamenteuse. Mais attention au prix/quantité, il existe en 2000 g ou 4000 Mg.

Finalmente sono riuscito a debellare la derbesia dal mio acquario. Avevo provato di tutto, senza successo. Al momento i miei coralli sono rimasti inalterati, speriamo continui così
