Thread: Is this algae?

  1. Default Is this algae?


    0 Not allowed!
    I've had this discoloration on just about all of my plants for a few months now and it's the bane of my existence. A beautiful new leaf grows in and is swiftly with this ugly stuff. My Amazon Swords and Wisterias seem to get it the worst, and the Java Ferns get some of it as well, but weirdly the moneywort (which is not a particularly healthy plant) is showing none of it. None really on the anubias, either.

    Scrubbing doesn't seem to do any good - when I scrub the leaves I only damage them while taking off none of the stains.

    I've attached a not-so-great picture below. It's kind of hard to tell, but I'm referring to the black and brown patches near the tip of the leaf.



    Ammonia and nitrites are are effectively zero, pH is around 6.5. Nitrates build up to around 5ppm every week but I'm pretty good with water changes.

    I dose with Flourish Comprehensive and Propel Iron twice a week, and Flourish Excel every day. I also inject DIY CO2, though the injector is a work-in-process and I haven't got it working reliably yet. I used to dose phosphorus, but I got black beard algae and stopped - between pruning the leaves and my Siamese Algae Eater I think I'm getting that problem more under control. I've got root tabs in the substrate near all of my swords, and an inch of Flourite in the substrate. I'm giving the tank 8 hours of light a day (around 2 watts per gallon, 6500K). I feel like I'm getting decent growth out of my plants, I just wondering if there's a nutrient I'm missing.

    In addition to the SAE I have 4-5 Otos in there, though they seem to ignore the sword leaves.

    Thoughts?

    A lot of the time those kinds of spots are caused by the plants being poisoned by something. Fish medications, untreated tap water, over fertilizing. So if you haven't treated your fishes for some kind of disease, and you always dechorinate your water, maybe you could try cutting back on your fertilizers.

    Is it furry or does it look more like a burn?

    If it's furry it can be a brown algae. A burn then it could be like escamosa said. Something poisoning them.

    That's a lot of fertilizing going on in a sparsely planted tank. I dose my tanks one time a week after their water change and one more time in the middle of the week and my tanks are jammed full of plants. I don't think you need iron in the water plus iron in the root tabs, as well. Swords need the root tabs.

    But really, some plants just don't do as well for us as others. Those that do well, we get more of and toss those that don't. Plants also like plants substrate and don't do as well growing in stones. Note I said "as well."

    Do you have a phosphate tester? I would never dose phosphates without testing for it first. It comes from my tap water at 2 which is far more than needed plus phosphates also is in the fish food.

    According to your other posts here, didn't you just get these plants a couple weeks ago? That appears to be black beard algae to me.

    Could be black beard algae - I've definitely got it and I usually prune any leaves with the ugly black growths. Can BBA also manifest itself over the surface of leaves, rather than just in those fuzzy little growths?

    I agree with Lady Hobbs about you doing too much ferts. Also, your light level is moderately low (2 watts per gallon and what is the temp?) Using CO2 is achieving little. While algae can do very well with low CO2, it isn't gonna mind extra; especially since the plants won't be using much under those light intensities.

    I'd raise the light intenisty, drop doing the liquid Fe, and cut back on the ferts. Also, maybe get more plants - this will use up the phosphates (a real driver of algae! Seachem sells a kit to measure this bad guy) and these will also help lower the nitrates even further.

    I would like input on this idea before you maybe trying this idea but couldn't a bleach solution (15:1) be used as a dip to kill algae off the leaves? Don't dip the roots, however. If well rinsed and soaked in water afterwards before putting back into the tank, I'd think this would be safe.

    I'm not sure I have a lighting problem, though I guess it's possible. I only give the tank about 8 hours of 6500K light a day and I can see new growth every time I come home from work. The Wisteria has already outgrown my tank height.

    Temp is usually kept at 79-80.

    I wasn't saying you have a lighting problem, only that for the light you have is too low for CO2 addition to be of any use. More importantly, the amount of ferts you are adding will cause algae. Your eight hours and color temp are fine. Sorry if I was not clear ...

    Well, my tank size sort of limits how much I can upgrade my fixture, but I did go ahead and order 2 24W 6500K GE bulbs, which should give me a bit of a lighting boost versus my crap Odyssea bulbs.
