    Moved the thread from my tank thread...

    In the last month that I have been away, lots of stuff has started coming out of the LR. May also have been help by the more than normal feeding routine of my caretakers.

    Going to post a few picks of the stuff, would appreciate IDs and views on if I should take action or be happy.

    1st, is a red algae, large leaved, nearly paper-like structure. Growing slowly but constantly. Kinda pretty.

    2nd, on the same piece of rock, a green spaghetti like algae. Growing very, very slow and has gone back since I started managing the tank again. The reddish hue is still from a bit of cyno. Looks wormlike.

    1. No idea

    2. A bit blurry but I think I can see feathery strands, google Bryopsis algae, if it looks like it then I would take that little rock out and throw it in the dustbin.

    1. cool
    2. green not cool.

    is this the only green stringy algea in tank? if so chuck rock as per viper
    if there is more. spray rocks with turkey baster to lift sediment into water column and do water change. then dose magnesium to get it to a level of not more than 1800Ppm (over 2000 ppm kills snails) and shorten your light cycle a bit. purigen and phosguard are cheapish assistants to drop the real problem which is possibly nitrates or phosphates. the other alternative is lightbulbs getting older so kelvin rating coming down. most importantly feed less for a while and do more regular than usual water changes.

    No, not Bryopsis, been there, done that. It is the bit to the left of the red one.

    It is a small specimen, about 1cm diameter in total. Will try to get a better pix.

    Not having a problem with algae, this is just precautionary investigation. Would like some macro algae in DT, so would like to keep this if OK.

    Have two other specie of macro algae in the DT, also small amount, still trying to take pix.

    Regarding the green algea

    No, it is very thin, about 1.5mm in diameter. For size, it is a Neon (cleaner goby) of about 1.5cm below it.

    Nearly looks like cheato, but grows in a roset formation.

    Are you sure it's not Bryopsis...I just found this on the Web...:

    Taxonomic Background
    There are at least 50 species of Bryopsis (including varieties and forms), but only a mere seven species are commonly found in tropical waters, plus three varieties of one of the most commonly cited species:

    Bryopsis corticulans ...this one does a "rosette"...move mouse over picture..
    Bryopsis index obviously I'm not saying it is that one, but would you consider it could be a "different" type maybe..

    Bryopsis corymbosa
    Bryopsis halliae
    Bryopsis hypnoides
    Bryopsis indica
    Bryopsis pennata
    (Bryopsis pennata var. leprieurii )
    (Bryopsis pennata var. secundata)
    (Bryopsis pennata var. secunda)
    Bryopsis plumosa
    Bryopsis ramulosa


    And this on MASA..:

    The Bryopsis thread. - Marine Aquariums of South Africa

    I am very scared of Bryopsis, lost a tank to it before.

    This does not look like any form of it I have seen, think it is a form of calpura.

    THink I should just play save and remove it, but will loose the red one as well.:(

    Can you not chisel the LR in half..? Don't think it is that hard...or place a screwdriver in the middle and whack it with a hammer...?

    Will make a plan, may even see if I can take the red one off and glue it to another piece.

    Hates killing something if it has not been 100% found guilty.

    I've had a look in my algae book, have a google of these, see if it helps.

    Enteromorpha

    Cladophora or Cladophoropsis

    Valoniopsis

    Enteromorpha sp.

    Hi

    For the green alga, I first thought it was Valoniopsis, but ENTEROMORPHA SP. is a perfect match. See here http://marineplantbook.com/marinebookenteromorpha.htm

    [​IMG]


    So what now? It seam to be fairly benign, is on a separate piece of RL, not growing. Do I keep the green one?

    Next to takle the red one. This one is actually still growing and depositing some leaves into the system, none of them has managed to attach in new spots. Looks very pretty and "natural".

    So you agree with me that it's that one...I wasn't sure, as you got the actual plant and knows exactly how it looks...:p
    I read that it's palatable to Fish, so...even though it grows fast, you might be able to "control" it with Fish....I would assume if you have the Fishes that eat them, you should be ok....if not, then I guess you can remove it manually...I don't really know, hopefully the guys with Refugiums can help you...:p

    Hi, yes agree, the link is your top link (came out different on as your display).

    Think my fish is to small to eat (enough) of it.

    Running my tank at zero nitrate and phosphates so algae is struggling in the DT (but by cheato is still growing wild in the refugium), all but the red one is dying back.

    Main risk is when I am on holiday and the house-sitters feeds a bit to enthusiastic again.
