Yes, I would recommend this.

Brown Algae

Pros: will get rid of diffacult algae

Cons: Do not use at full strength.

I had brown in my saltwater tank. I have been using algaefix Marine for 2 weeks now and the algae is gone. I used half the strength it states to use. I also took 5 gallons of water out of my aquarium, then I mixed 5 gallons saltwater and put the dose in with it so that the fish did not get the dose directly in the aquarium. It works great. Do not use at full strength.

API Algaefix Marine!

Pros: Quick and effective results. Reef Safe.

I've used this product and has helped me control algage in my own tanks. Algae problems are frequently related to excess of nutrients or light, so it is important to determine the source of the problem and make the necessary adjustments. I recommend using Algaefix to quickly eliminate the algae from the tank and then by eliminating the source of extra nutrients or excess of light the algae is not going to continue growing. Other methods may be required to prevent algae from growing back such as using GFO in a Media reactor to reduce Phosphate Levels.
