    Hi,
    I have a non-co2 50g tank that have a green hair algae problem. I usualy get rid of that easily but for that tank, it seam to want to stay and grow.
    I do my water changes after the light are closed,
    I do not overdose ferts
    everything seam ok
    but there is that green haire thing who chalenge my nerfs

    Can you help me with this?

    There is also an other thing:
    It do not look like a alga. it's more like a fungie. it's broun. It's not growing but it stay there, sit on my java moss. It grew up one night and it have been there for the last 3 weaks.

    Do you dose any macros or traces, say once a week lightly?

    That can reduce several species of algae.
    And grow the plants better.

    See the ref to the non CO2 tank methods I have in the article's section here.
    Hair algae and a the other sound like not enough nutrients, things are good, but too lean over time.

    I get hair algae when I leave for vacation for several days/weeks.
    I do not dose but everything else in in place.

    Regards,

    That and adding more herbivores often helps.
    Excel if you get desperate.

    Generall ythe growth is slow in non CO2 tanks, so I have little trouble keeping up manually removing algae and the tank gets better with a little care and dosing, so it's not an issue later.

    Hi!

    I decide to try my old test kit and tested the water just to make sure I do things write.
    I was doing that same fert routine for the last 6 months.
    I realised everything was perfect (maybe a high No3 but nothing freak) but after a weak, Fe was all gone.
    It might be what was the problem! I havent notice that before (wonder why) but It's easy to think that Fe was missing on weak every two weak for the last months. So I now put more and we'll se if it help.
    I also add 10 yamato shrimp. that will help I'me sure.

    Since it's a non CO2 tank, light dosing once a week is about right to prevent the plants from missing any one of the 17 essentials.

    Non CO2 tanks are very forgiving but not indestructable, the small frequent dosing will help, the goal is to not go too far the other way, a low level limitation is not bad here, whereas in a high light/CO2 tank, it would give you real issues.

    If you calibrated that test kit for NO3, you might be albe to back off the N dosing and go namely PO4, and TMG, or alternatively: TMG and GH booster from Greg Watson. Fish food can prevent critically low N and P levels, but you still need the Ca, Mg, Fe, K+ etc.
    The GH booster adds all of these.

    sorry i forgot to tell: my Fe mixt include also others traces.
    so that was missing to.

    I think I did not ajust the routine enought after the plants had grow and most important, I should have ajust that routine after new fish were add.

    I think some cleaning on your part to reduce the Hair algae back some, a little dosing, Fe will not be measurable anyway after a couple of days......TMG will last longer than Flourish certainly and is a better trace than Floruish for such tanks.

    You will do good to get some critters to munch on the algae, they are more effective in the non CO2 tanks since algae also grows slower.

    You can also do Excel spot/general treatments for a few days and then back off.

    Rather than dosing every other day etc, dose just once a week for awhile and then spot after the algae dies back.

    You do not need to be very agressive with non CO2 algae issues, they are slower.

    I have done a good cleaning, add more plants (cabomba), add fert once a weak and even clean that filter that was dirty like nothing (forgot about that one for 6 month).

    I feel that green hair algae is not as well as it use to be. good think but I still have that cyano that comes once in a while. I never had that one before I give a try to non-Co2.

    so now, I am trying to find whats wrong:

    volume: 50g
    Fish: 4 sylver dollard, 14 lemon tetras, 3 cory (?), one female beta.
    light: 96w 6500k RCI 80
    Substrat: to mutch peat moss (2 inch) but I boild it before so it should be ok. over top of this there is a good 2 inch of sand and gravel.
    Plants: lot! Cabomba, java fern, java moss, ludwgia repen, e. tenelus.
    Ferts: I add about 15 ppm a weak, Po4 about 1 ppm a weak, K about 10 to 15 a weak (sometime I forgot that one but there is some in my kno3 anyway), Fe about 0.25 to 0.5 every weak and that mixt contain other trace.

    So I read again the non-co2 methode. It's said I wont have algae with an excess of N-P-K and trace. It's said that I will have algae with NH4. It's said it should be ok:D .

    So i'me thinking about NH4 now. so I give my old test kit an other chance to show me I need it and the result was that I do not have any NH4. It's said there is nothing but I do not say if they was NH4 yesterday or 2 days ago. so maybe thats the thing. How would I know if NH4 is a problem?

    96 watt of PC lighting on aq 50 gallon non CO2 is way too much.

    Try 2-3x 30w tritons instead.

    ha ha! so it could be it. I thought 2w/g was good for non-co2. well...

    so you dont think it could be a NH4 problem?

    2w/normal output, but those 96w PC's run hot, about 2-4x as much light as a no T12/T8.

    Yes, those are no less than 2-4x the same = in NO T8 lighting.

    That is a lot of light for a non CO2 tank.

    Powercompacts are high output, the higher the wattage, the higher the amount of light that come out of them also.

    So a 13 w may be = to a normal ouput 15 w FL light
    a 55 PC light= 100w NO FL's
    a 96 = 300w NO FL's etc

    Not that much, but close.

    :eek: Oh i'me far from what I want.
    I took off the reflector. It's way less bright like that. If this is not enough, I'll higher my light a little.

    thx for the advise.
