    Red Algea Good Or Bad

    Hi Everyone,

    Ever since I bought my tank over 3 years ago there are two rocks that are completely red. One is still red and the other is red but know has spots that are really red. I use only RO/DI water since the beggining. My brother saw my tank and thinks the red algea might be bad so my question is, is red algea bad and if so how do I get rid of it. I will take a picture of it tommorow.

    Thank You
    Terry

    if its slimy then its cyanobacteria. just increase flow in your tank, reduce feedin/ phosphate and also syphon as much as you can out as possible
    I had this problem and had just finallyt fixed it after like 4 months of trying. I increased the flow to my tank and reduced phosphate . at first they didnt go away when a syphon a lil bit but when I syphon all that I can see, they didnt come back. at first b4 when I didnt increase my flow, When i syphon it all out they would come back, so I suggest syphonin out as much as you can and increase the flow in that area. if its on the sand get a sand siffter.
