    My tank was infested with long green algae. Length can be as long as 8 cm U can also see it concentrated at the Riccia.

    Just wondering what are those and how to get rid of it??

    Manual removal: use a used tooth brush and twirl up the strands or use your fingers to pinch off the ones that grow in a wad.

    Maintainance crew: platys (pretty effective in my experience), mollies (never tried), pencilfish(not effective in my experience, but I think I got the wrong species).

    Algae grow when there is an inbalance of nuitrients in the water.
    You need to figure out which ones are lacking or in excess and either compensate by increasing shortfall or reducing excess. Easier said then done. A common one is shortage of K (pottassium). Have a look at "Control of Algae in Planted Aquaria" on TheKrib.com.

    Why use punctuation? See what a difference it makes:

    Hi PC, those that got stuck in the Riccia will be very hard to remove. Suggest salvaging whatever you can and throw the rest away. I can't remember how my hair algae went away but it will pass. You can try growing some of the Salvinia to block excess light as well as suck up excess nutrients.

    Some say Yamato or Gouramis eat them. I am not so sure.

    yamatoes will clear them
    don't overfeed the yamatoes or they might not want to eat the algae

    My guess is that you have excess nitrate. New tank?

    Thks for the response.

    Will measure the Nitride level when back from Taiwan.

    Suspect due to over-feeding during my absence as my son kind of over-feed the fish.

    Cheers

    I had always thought of NO3 as the culprit. But recently, patches or short green hair/wool like algae are growing in my tank. I left those at the back on the black styrofoam alone as it's quite nice. The same thing for those on driftwood as they form a nice green layer ... nicer than my hava moss ! Some grow on the gravel which I removed. Those on top of my Riccia is a result of lack of CO2 as riccia slows down and they took over. I removed and threw away the riccia. All these while my nirate is at a very healthy level !
