Product Description

Algaefix Marine controls a wide variety of algae types in marine (saltwater) aquariums, and is EPA-registered as reef-safe. It will not harm marine fish, corals or other invertebrates while eliminating algae growth and keeping your tank clean and clear.

  • Safe, effective algaecide for saltwater fish tanks
  • Controls many types of algae in marine and reef aquariums
  • Will not harm marine fish, corals or other invertebrates

When used as directed, Algaefix Marine effectively controls green algae, "red slime" and "brown algae". Use in saltwater aquariums containing live corals, invertebrates, and fish. It will not harm coralline algae, discolor water, or cause foaming.

Treats: 1 ml treats 10 U.S. gallons of water or 5 ml for each 50 gallons of water.

Directions: Add 1 ml (1/5 tsp) for each 10 U.S. gallons or 5 ml (1 tsp.) for each 50 U.S. gallons of aquarium water. Repeat dose every three days until algae is controlled. Siphon or scrape any dead algae from the aquarium. Once algae growth is under control, add one dose per week. Weekly doses of Algaefix Marine will control algae growth and reduce aquarium maintenance. It is a violation of federal law to use this product in a manner inconsistent with its labeling.

I love it

I have an SPS & fish tank, an LPS & fish tank, and a fish & live-rock tank, I used Marine Algaefix for all of them. Some worked faster then others. After 1 month, all of my tanks looked good, no algae any more. I did not understand why some one said Algaefix kill their coral & fish???

Works great

I was having a problem with algae growing on my one large piece of live rock. Since purchasing and using the product I've noticed the algae is at a minimum. One important thing to remember is that you need to scrape it off. I forgot that piece of information and couldn't figure out why it was still there. I've been using it for a couple weeks and have noticed a difference. I would recommend it.

Amazing Product

I had battled for quite some time with algae. I was always hesitant with trying a product to get rid of it, but after a year and a half of trying all the regular methods of algae control -- water changes, changing lighting, etc. I gave in an purchased Algaefix Marine for my reef tank. Within a week the algae was practically gone. It totally cleared it up and did not harm any of my coral.
