    Hi there so my tank is covered with brown algea all over the sand and live rock so bad that my polyps on some places doesn't want to open.

    So yes I've read about to much nutrients but I've tested my phosphates is at 0.1 and my nitrate at 0.5.
    Is that the problem?

    2 things I've thought of is I only have a small np reactor with 250ml pellets in for a 600 litre tank is that maybe not enough?

    The other thing is when I started the tank I bought live rock from a guy who battled with the same type of algea,did it maybe carry over to mine?

    I'm runnig carbon also,any help will be appreciated

    What skimmer are you using, are the pellets tumbeling?

    this seems a little high.

    got a pic of the algea?

    I am not much of an expert but someone told me to actually use a net and gather as much of the algae and physically remove it from the tank where ever possible. You might want to use a soft blowing pippet and just blow gently on your corals and polyps to remove some of that. I had the same problem and removing the majority like that helped clear mine. In some cases i had to physically gently brush some harder corals with a soft toothbrush to remove the algea.

    It helped for me and i no longer have that problem.

    Can you post a couple of close up photo's? It could possibly be brown cyanobacteria.

    Yes phsical removal helps alot. But the problem can quickly return is the source of the problem is not found.
