Will this work on brown algae

API Algaefix is the top selling algaecide in the aquarium industry. API Algaefix Marine will treat brown algae as well as string algae and many others types of algae as well.

I accidentally ordered this instead of the Algaefix for ponds that I normally use. The ingredients look to be the same are they in fact the same?

Yes, all Algaefix ( Pond, Marine and Aquarium) are all the same product. Dose as normal.

Can I use this in my saltwater reef aquarium

Yes I have freshwater aqauriums and planted tanks

I used algae fix in only fish marine aquariums and worked good but wit the time a black algae got. Why that happen and what can I do?

Keep treating with algaefix ( although chemicals can be a bit stressful on the fish, therefore the duration must be limited). More frequent water changes. Usually one algae replaces another. It’s a very hard battle to get ahead of. Check your filter to ensure you’re getting the proper turn over rate. Changing the food, and lowering the amount entering the tank. Also, reduce the amount of light (direct light and from light source) in addition to the amount of hours the lights are on. Use a sterilizer capable of level 1 sterilization, 24/7. All of these things combined should reduce the amount of algae.
