API Algaefix Marine, 100 gram

Fine

Good

I used it many times as per instructions ... But this is really useless for fish tank ... It have no effect on clearing water and removing algae.. but at same time my fish acts like sick and don't eat after using it .. really harmful for fish ... Can kill fish ...

Despite reading bad reviews on this we chose this as it still seemed like the best way to cure algae. So we under dosed the medicine compared to what website and the product description said. 1ml for 20 gallon. Simultaneously we changed water 25pc, added stress coat. It worked like wonders - tank was clear in 4 hours and 18 hours post the medicine, fish still seem in perfect health

After 1use I can notice the algae dying in the fish pond. We had a big problem with algae but this product seems to be fixing the problem.

I downsized from a 65g reef to a 28g cube last summer in preparation for a move. Because of everything going on, the tank was neglected. Within a month or so of neglect, some caulerpa macro algae had taken over the tank. It must have been a hitchhiker from the sump of my previous tank. I was literally filling up a 2 litter pitcher with algae every week as I was pulling it off of rocks and trying to get things under control. I was about ready to throw in the towel, boil all of my rock, and start over, but I decided to give AlgaeFix a chance. It took a few doses before I noticed anything, but probably late week 2, my skimmer started picking up a lot more "gunk" in the water. Over about a 2.5 month period, it has reduced the caulerpa by probably 90% and has it down to a manageable amount that I'm trying to eradicate through regular water changes and proper levels. AlgaeFix saved the life in my rock and saved me from giving up. I know a lot of people have asked if it will kill macro algae. I can confirm that the answer is yes, but it will take a long time before it wipes it out. I'm fully confident that you could clear up a hair algae breakout long before you decimate helpful algae in your sump. Great product that I will keep on hand for as long as I have reef tanks. Thanks!

This product Algae Fix Marine has the same ingredients as the one for Fresh Water fish tanks. I have used both. They work very well. Corals, fish etc are not affected by it. I believe Vibrant is the same, but much more expensive. I don’t know why I bought such a big bottle as I only need 10 ml for 100 gallon marine tank.

Had a small but growing infestation of bubble algae. Took a couple of months - but it’s all gone!! Now I just dose once per week to make sure it doesn’t come back.

NOT SAFE FOR CORAL. WILL NOT KILL HAIR ALAGE . WILL KILL YOUR FISH AND CORAL Do not use this chemical NOT REEF SAFE!!! Killed all my corals in three days. YES I USED PROPER DOSE !!! Followed instructions on bottle to the letter. This did not help at all. DECIMATED MY AQUARIUM. IM DISTRAUGHT AT WHAT THIS HAS DONE. YEARS OF HARD WORK DESTROYED IN THREE DAYS.
