    hi

    i bought some lr from a fellow reefer and it came with this algae on it, was told its not a problem, anyway it seems to be growing and spreading. its growing on my powerheads, on one two other rocks and the tank itself.

    what should i do with it? is it good or bad? leave it or take it out?

    if i have to remove it, whats the best way of doing it? can i get some fish that eat it?

    iv currently got 5 green chromis, 2 cleaner shrimp, 2 fire shrimp and a hermit crab

    thanks

    Don't know the size of your tank and if its good idea to get a tang, but my tangs take my algae out, quick quick.

    Well, if it is spreading/growing then you have a nutrient problem. What are the nitrate and phospate levels at?
    If you feed frozen foods, how do you do it?
    How old are your light bulbs?
    What filtration do you have?

    Sorry for all the questions, but trying to filter out the cause

    Thanks guys

    @philip. Tank 1,5m lng. 80cm high

    @Tobes. I'll try doing a test tonight if the nitrate and phosphate levels are high wht should I do?

    Iv only fed frozen brine and that only about 3 times. I let the cube melt in a net in the tank and then release it

    Iv got a octo 160 int skimmer and a dsb

    Iv got two t8 bulbs only waiting for my mh. Both the t8 are actnics

    By feeding that way, it might be the cause of algae growing as the juices of frozen foods is like fuel to them. Try this:
    Take the frozen cube and defrost or thaw it in cold RO water in a glass. When done, pour through a plastic tea strainer and discard the water with juices. I then rinse the frozen foods with a little bit of tank water. Then you can feed :)
    Reason for cold RO is so that the frozen foods does not loose too much nutrients.

    Oops, wanted to say that in big systems with lots of filter feeders this won't make a difference, but smaller systems might get affected.

    It looks like derbesia but like mentioned, the start of nutrient issues.

    @Tobes
    Shoo that's alot of work for the frozen food.

    Will a tang eat it?
    If yes what tang would be best?

    It takes me a few seconds to scoop RO in the cup and put the cube in. Wait a few min to thaw out and pour through the strainer, rince and feed - it's like 5min? Not much work, but worth the little effort :)
    I haven't seen a tang eat long hair algae, when it starts to grow yes, but not long.
