How to control on brown algae?

Hello friends..
I have not been on this forum for a little while, hope you all are having good time. Well, I have lot of brown algae growing on my rocks and some on my sand. I have never seen this brown algae in my reef tank ever before. Is there any way to prevent this? Just wondering how safe are algae products for soft corals? BTW I don't think it is Cyano. Does anyone know what's wrong going on and how to stop it?

Thanks for your help.

I wouldn't jump to the use of additives. If you're having algae problems, something is out of whack. IME, brown algae likes phosphates. I had a bad problem for a while, and after the addition of a bag of phosban (in a reactor would be best) and a couple water changes the problem was resolved. Get a test kit and see what your levels are. If there is even a little bit it can be a problem.

Are you using RO/DI water?

Nitrates will also help out algae so try to keep that as low as possible too with water changes/feeding less.

Hope some of this helps. Hopefully someone else will give you more suggestions.

How old is your tank?

 

Excess nutrients like phosphate, nitrates etc. A dirty filter often traps nutrients What is your photo period ie. how many hrs/day do you have your lights on? A good CUC will probably help control the algae, too??? There are some commercial dry foods also contain excess nutrients and other undesirable things like nitrates, phosphates etc so I strain/rinse my fresh/frozen foods before feeding my tank. You can add a phosphate remover and increasing flow in your tank. Also using RO/DI water and a high quality salt with minimal NO3, phosphates etc like Tropic Marin will really help too.
