    Hi

    Does anyone know of a good method to clear this stuff up? I know i should be looking at the source of the problem and not the symptom, but this stuff does not die easily.

    CO2 is good , tank maintenance is up to scratch,i do a large water change every week and syphon all the nasties out. Flow is also good....never had this type of algae, was always struggling with BBA and staghorn, now that they are clearing up this stuff appears and no matter how much i manually remove it seems to come back with a vengeance.

    What i have done so far is , i raised my lights about 3cm higher , cut the lighting period to 7 hours and upped the CO2 to the point where my fish is gasping at the surface and turned the CO2 down just a little bit so that the fish are still happy and not showing any signs of stress. Have not tried H2O2 because last time my MC melted and it just started recovering now.

    Any suggestions are welcome.

    Thanx

    Is the room quite bright during the day or maybe even some direct sunlight?

    @GroenVissie not to bright during the day and there is no direct sunlight on the tank.

    @Adrian i will cut the light to 6 hours and check what happens, i know changes dont happen fast so i will have to change 1 thing at a time to pinpoint the root of all evil. Lol

    Thanx.

    I have 3 ottos in the tank but they dont seem to be interested in the rhizoclonium.

    I redid the tank in january with the microbe lift substrate so its about a month old now and i used the same filter with filter medium.

    I also think it might be my lights thats at the root of my algae bloom. Will see if i can raise them a bit higher and set the timer to 6 hours a day. Running 3 X 30w LED flood lights on this 3ft , i think it puts me in the high light category.

    Have you considered a "siesta" period? Basically halve the time your lights are on,then turn them off for 2 or 3 hours and then give them the other half of the light time. Dont know if it works or not but I have been using this for years. Lights on in the morning for 4 hours, off from 14:00 - 17:00, on until 21:00.

    Thats how i ran my lights on the tank before adding CO2. Then i changed it to 8 hours straight. Was scared the CO2 would build up when the lights were off and cause CO2 fluctuations.

    Are you running CO2 with your siesta period?

    No, no CO2 for me. I have never liked the idea of CO2. Why do I want my plants to grow faster just so that I need to do more maintenance more often and end up throwing/giving plenty of cuttings away? I am really lazy when it comes to this so most of my plants are crypts and anubais. No stems as I kept allowing them to get out of control.

    I agree with that. Depends what you are trying to get out of the hobby I suppose. I am quite happy to give those plants a skip and stick to less demanding plants. It takes longer for my tanks to fill in but i am in no hurry. Others may not be. Its what makes all our tanks diverse and interesting.

    Ok cool , ill do some research on the siesta period with CO2.

    Dont want to change to much stuff at once.

    I ordered scape liquid carbon, going to try and use it to treat the symptoms, figured it would be better to use scape than h202 whil trying to sort out the root cause.

    Tank is starting to look better now.

    Lights raised , roughly 15cm from surface, light period down to 6 hours.

    Method for treating the symptom: whole tank H2O2 treatment, 3%H2O2 50ml dose on 100L tank , running filters without filter media for 15min and 70% water change , followed by 3day blackout. (No loss of life)
    Manually removing rhizoclonium with old toothbrush (uprooting most of the MC) this stuff was very sticky.

    Algae crew helping alot , otto's and SAE finishing of the last remaing algae.

    Thank you all for the input.

    Will see how it goes now that the symptoms has cleared. Hopefully the root of all evil has been delt with.

    CO2 ran empty today , starting scape liquid carbon in the meantime till CO2 is refilled. Hoping this wont spark another algae infestation.

    once your plants are clean, its easier to remove the SAE while you still have some space, once they get bigger, they stop eating algae, and just turn into fish food eating bullies..
