    Seem to be getting a bit of a staghorn algae breakout on my tank.

    Its a 70 litre tank Heavily planted.

    pics can be seen here Speedingorange.com | Just another WordPress site

    at first it was just a few tufts of staghorn but it is spreading. I have been plucking / wiping it off where possible and doing frequent water changes to cut down spores.

    I dose Tropica plant nutrition + once a week at 4ml

    I also seem to be getting a bit of Oedogonium? on my glass.

    Lighting is two juwel high light bulbs 24W 8 hours a day.

    C02 injected for 7 hours a day starting an hour before the lights come on.

    any help much appreciated!

    Did you try glutaraldehyde? Depending on the species sometimes that works.

    It is a chemical most often bought in the product by Seachem called Excel. There are ways to treat it with H2O2 (hydrogen Peroxide) too.

    I have some hydrogen peroxide on the shelf that i use to clean my Co2 diffuser.
    Would I dose the Seachem Excel along side the Nutrition +?

    Hi,

    Usualy staghorn algae is due to very low nitrates. You must fert with Nitrogen and keep a good water flow. Unfortunatly I have a lot of experience with it

    Hi, staghorn is an indication of not perfect co2 distribution and/or lack of maintenance such disturbing the substrate without a water change afterwards, dirty filters etc.
    That is the easiest algae to get rid of and it rarely comes back, at least to me :)
    Increase the maintenance.
    I would start co2 2 hours before light on or even 3, gas is cheap ;)
    Gluteraldehyde containing product as said before will kill it very easy. In uk the cheapest option probably is Liquid carbon from aquaessentials. Others are seachem excell and easylife easycarbo. None of them will tell you it contains gluteraldehyde though as it is nasty chemical :notme:
    I think 4ml of TPN+ a week is to low as well. Have not used commercial ferts but i would assume you want to dose daily close to that dosage.

    Hmmm,

    I actually backed off the dosing of the TPN+ as I thought that may have been causing it. I was dosing at 6ml per week previously.

    I wonder weather it is worth me switching to a different fert?

    the box says to dose 1ml per litre every week and do a 25% water change every other week to remove any excess.

    Maintenance wise I have the following routine.
    20 litre water change every week inc cleaning filter medium
    after changing water I dose ferts.

    I cant do much with the substrate maintenance wise as the whole tank is thickly carpeted in either HC or hairgrass.

    C02 distribution should be pretty good and the staghorn seems to be worse at the end close to the diffuser.

    anyone any suggestions as to what ferts I should try for daily dosing? alongside liquid carbon?

    Nitrates tend to sit in my tank at around 20-40ppm is this low?

    AE Design Aqua Nourish Range 250ml £15.99 - Buy Freshwater Accessories

    or

    http://www.aquaessentials.co.uk/ae-design-aqua-nourish-set-250ml-p-4245.html

    I only have normal testing kits for nitrates hardness etc so tracking Phos and nitro may be a little hard? or do you think it may be worth it?

    Thinking of getting this and doing away with the plant nutrition +

    I am wondering whether the TPN+ contains the macro elements and not the general ferts needed?

    The other thing is some of my plants that should be going red (blyx japonica) are maintaining a healthy strong green... what would cause this?

    TPN+ is good fertilizer. You definitely dose not enough.
    People often use IE fertilization method with dry salts because it is min 30 times cheaper than buying commercial. Just google it.
    There are starter EI kits available from plantfood.co.uk
    Water changes have to be done at a rate of 50% weekly. And if you have algae increase that to 3x 50% a week.
    I would start dosing tpn at 5ml daily at least, switch co2 2 or 3 hours before the lights and increase water changes to 50% every other day for couple weeks.
    Regards.

    P.S. Dosing recomendations on the bottle are for people not using high light and what is more important co2.
    TPN+ contains all macro and micro nutrients.
    Like i say you want min 4ml daily dosage.
    Photos would help as well ;)

    What photos do you want?

    Just of the general tank?

    I will try upping the dose to TPN+ to 3ml first to check for no bad effects. C02 will be kicking in an hour earlier tomorrow (2 hours before lights)

    30 litre water change sunday.

    See where that takes me :)

    Hehe...
    How old is the tank btw and what substrate is that?
    Blyxa would go a bit red only under extra strong lighting.
    It is looking nice.

    Well if tank is that old and looks great then you were doing everything right probably.
    I assume that staghorn might be just a consequence of dirty filter or any other maintenance problem. Maybe you have replanted some plants without water change or something.

    I wouldnt change much if it was going good for 8 months.

    Hmmm ok,

    I will maybe stick to my current routine, but dose in small divisions daily instead of all at once to add stability.

    What about the green thin hair algae i am getting some of on the glass? only seems to happen on the one side of the tank? (this does get a small amount of natural light)

    Might be indeed due to natural light.
    One more thing i wouldnt trust any test kits ;)
    Unless you calibrate them which i dont think you do.
    Majority of people dont ever use any tests on planted tanks.
    these days the goal is to go for unlimited ferts.
    Get your plants to grow healthy and algae wont come.

    so what would you do in my shoes? try some of the liquid carbon just to help nuke the staghorn? then keep doing what I have been doing but dose the ferts daily (7 x .6ml ) ?

    I would probably keep increasing tpn more slowly if it worked for you all these 8 months. mb 2-3ml per day and observe plants. If you see improvement can add more and see if it does any more good.
    Increase water changes.
    Easy carbo would help to get rid of staghorn very fast when overdosed 2-3x of recommended dose for 3 days or so. or just spot dose with syringe if there is not too much. It can also be removed manually.
    Your tank looks really healthy ;) Maybe just increasing waterchanges alone would solve it.

    Just ordered some Easycarbo, should be here tomorrow,

    Will start dosing it at double strength and will be increasing the dose of TPN+ as of sunday also.

    Will post some pics later of the algae. I want to nip it in the bud before it really gets a hold.
