Thread: Algae on gravel

  1. Default Algae on gravel


    0 Not allowed!
    Now that my tank has been established for about 5 months now I'm noticing that alot of my gravel is turning a greenish algae color. It was brown but now about 25% of it is brownish green. I vacuum it every few weeks in spots. What do you guys do to keep it clean. Should I remove it a little at a time and bleach it or something?

    oh oh. Sounds like you are getting some cyano algae. Gravel needs to be cleaned more than every few "weeks". Cyano is a bacteria.

    Should I remove the greenish gravel and bleach it? It doesn't seem to bother the fish, it just looks unsightly.

    You do not want your fish eating it. If those are all fake decorations, remove and soak them in some bleach water and start vacuuming that gravel. If you have to remove the area's of gravel, then do so and also bleach it. Make SURE everything has either been soaked in some dechlorinated water afterwards or air dyed so all chlorine is gone before replacing.

    At least, that's what I would do.

    Ok. I've been removing decor once per month and soaking it in bleach. The gravel around the decor is usually what is green. What ever was under the decor is still new looking. I guess I'll just remove the worse looking gravel rocks and replace them. Problem is that my tank is in the middle of my house and gets hit on both sides with sun. Not direct sun but if def gest some light.

    Light is fine, direct sun is not. But I don't believe Cyano is sunlight related but bacterial.

    Oh no. Is it a threat to fish. I'm now wondering how my cories will handle being around it all the time.

    I have had extreme success with flourish excel(from seachem). It actually is a
    carbon supplement for plants but for whatever reason it also kills algae.
    use a syringe to squirt it wherever you have blue green algae(cyanobacteria) and
    by the next morning what used to be blueish green will be faded brown.

    Keep in mind though that while excel kills algae it does not address the root cause
    of it. blue green algae seems to appear in my tanks whenever I feed more than usual so you may want to try cutting back on food and, as Lady Hobbs mentioned, clean out the gravel more often.

    Awesome. I'll check this out. I do tend to feed too much so I will cut back. I try to clean the gravel half one week and the other half the next.
