    Hello reefers... i have had my tank running for almost a year now. there is no algea in the tank except between some polyps and zoas! now i dont know wht this algea persists and the other algea in the tank disappeared?

    My question... how do i remove the algea? i cant brush it off cause it will kill the polyps. Whats the best way to kill this green hair algea, its stunting the growth of my coral as they cannot open fully.

    any help will be appreciated... :)

    Are the corals on rocks that you can remove from the tank...?if so you can remove most of or all the hairs outside the tank in a buket with some water in it ..tha corals will pull back and you should be abel to get inbetween with a tweezer or fingersor small brush to pull algea of ...doing it in a bit of water will help you get hold of the hairs more easely...

    Agree with @jacoc, also check your PO4 levels.

    if you have time and are willing to invest in a slow cure id set up a small tank (60l) or so with low nutrient content (no fish or feeding etc and some mechanical fuiltration system to export nurtient) and house the corals in there for a while so you starve the algae to death. Manual removal of the longer strands of algae will leave the base to grow again, especially if they get food from your water collumn.

    i agree... thing is i have tried everything except that, i have taken the coral out and cleaned the :****: out of it, but algae keeps growing back.... i have measured my PO4 weekly for two months and it does not even register. i am assuming that the little PO4 there is is being used up by the little hair algae i have between the polyps. (the only place my foxface refuses to graze)

    comments?

    i dont feel a herbivor fish will help you in this case. with the algae set inbetween the coral they are not going to be able to get in at it propperly, hence my advice to try starve it of nutrient. the problem though is that algae are very good at nutrient uptake and need very low amounts to continue their growth.

    perhaps you could find a zeo based system near you and ask them to host the coral till the algae dies back.

    or you could start with carbon dosing (after 12000 hours of research first) and try drop the bottom out of the nutrient by increaseing the bacterial population and allowing them to convert phosphates and nitrates faster than they are at present.

    just different options as i dont think a fish is in your best intrest long term here.

    I suspect that a hermit crab or snails would happily remove it for you from between the polyps.

    Always try to remember that in nature something gets rid of this growth. try to find what it is. Trying to do a job like this yourself is seldom succesful.

    I think that the foxface with its fairly long snout would have done it already if a fish were the answer.:)

    Are you 100% sure it is definitely common hair algae?

    I also have a major hair algae outbreak - tagging along...

    Should a Scrubber and Phos reactor get rid of it?

    If you can trim of the long hairs by brushing or whatever way pleases you the tang will eat the new growth and maintain it...They don’t eat /pick at long hairs but will on new growth...also I find hair algae seasonal..It comes and goes...

    either of those will help lower phosphates. I thought you were already running phosphate remover?

    Have you changed anyhting that could have caused the outbreak?

    No, I changed nothing... In fact, I cut down my feeding from 3 times to twice a day, and made sure I feed less. My lights are on from 3-9 daily.
