    hello, i have a few Staurogyne sp plants in my tank & all of them have a almost black susbtance on the leaves, the new plants that come through are ok untill they reach a certain size then bam "black death", this does not affect other plants.
    i have tried to scrape it off but its in the leaf not on it.
    tank stats
    180 ltr
    1 x 45w juwel nature t5 tube & 1 x 45w arcadia j5 plant pro both with reflectors
    standard 600lph juwel filter + tetra tech 1200 ext filter
    ph = 7.2
    kh = 8
    gh = 10

    does anyone else use this plant?
    anybody had any problems?

    i dont want to bin this plant as it really is a nice plant, once established grows really well
    thanks in advance for any help.
    ps = would a pic help?

    Hiya, i've had this issue before and i think it's actually tiny holes in the leaves along with some sort of algae. I found that upping my dosing and doubling the amount of WCs fixed it, my was in an 11l nano so it was easy for me. I'll take a guess that your not using CO2? It doesn't effect the Staurogyne in my tanks with CO2.....

    When I first put Staurogyne into my tank most of the leaves became black - like green spot algae that I get on my anubias but black. Anyway, I found that by upping my co2 levels (as they were poor at the time due to a ran out FE), every thing's a lush green.

    One thing I have found is that I tend to break the stems when vac'ing the plants so just be a bit careful. I'm trying to make a staurogyne bush at the minute after replanting it every two weeks. Hopefully, it'll fill in nice.
