ID algae - unsure if it is brush, thread, filament, green, cyanobacteria algae

[ralliart12]

Hi fellows, I've having some doubts as to the true identify of this algae:

P1000300.jpg

Anybody knows what it is, 7 how I can terminate it (in a tank with 1 single continuous session of 12-hours of light per day & no water, as I'm deploying DSM)?

Thank you.

12 hours? Is it growing thick and dark green? My potted barcopa has alot.
Think 12 hours light period is alot haha.

It's a fungi I think. I don't know how you're going to kill it other than manual removal. I had these in an old bag of peat moss I forgot about. Fine strands that would trap dew drops or water on them, like a spider's web.

Remove the affected area, microwave the soil in a tub with a hole poked in the cover for ventilation. Let the soil cool down to room temperature, then rinse it again and use it, or just throw away the affected patch. You might have to kill the plant because the spores will be around.

12 hours? Is it growing thick and dark green?...

Will prefer to discuss this aspect in the HC-growing thread.

...My potted barcopa has alot...

Is it structurally similar to the one in the photo? Then may I know how did you remove it?

...Think 12 hours light period is alot haha.

Oh, is it? May I know how lengthy should the appropriate light sesson be, & should it be broken up into a few sessions?

It's a fungi I think...

May I know what's the deciding factor that cause you to conclude it ain't one of the more common algae I listed in the title? I will love more information.

May I just (thoroughly) bury that entire patch of affected area?

...because the spores will be around.

Erm, will it affect human breathing?

May I know how to curb such setbacks? i.e. increase air-flow?

Your counter question is on light or the way i describe the algae? you quote 2 Qns at one go... i cannot answer you as i cannot understand where your asking at. the below may

My barcopa tank i did nothing, i recently decom and reset in normal pots. Daylight hours , outside the house.
too strong light too long hours too damp compost (it was gravel+soil).
The pot i used was DIY from those plastic coffee boxes with, no way to drain excess water. like timebomb waiting to happen

Note: the above is assuming the algae is on the substrate, please neglect if your saying the fungi that looks like spiderweb.


The HC have mould growing on them, happen to alot of DSM using HC.
If DSM, maybe you can try giving some breathing holes? It would be good to offer a slightly larger tank shot as well. My recent HC attempt have fungi too , it was covered by cling warp and started just pior to hotter season.

Btw: i grew sick by the time all my fault were found and flooded + co2 when HC started to spread.

If it was an algae, the strands would be green since they basically are simple photosynthesizing plants. It is a type of filamentous fungi, of which I have no idea of the name. You can attempt to bury the affected patch, though I doubt it will kill the fungi. It'll just find a way to get back to the surface and burying is no guarantee of killing it. Might as well remove the affected area, and replace with fresh soil. Any bit of soil or plant that has the fungi should be removed. No idea on whether the spores, if any, will affect your breathing.

I see how I could have started my confusing approach of asking; when you initially responded:

12 hours? Is it growing thick and dark green?...

I thought you were asking if 12 hours of light is giving me a thick carpet of HC (or not), i.e. I thought your "it" refers to the HC on which the fungi/algae is growing on. I apologise for muddying the waters, so to speak.

...i cannot answer you as i cannot understand where your asking at. the below may

My barcopa tank i did nothing, i recently decom and reset in normal pots. Daylight hours , outside the house...

Wait, I'm unsure if I follow, so did you manage to rid your Barcopa of this type of fungi/algae in the end?

...too strong light too long hours too damp compost (it was gravel+soil).
The pot i used was DIY from those plastic coffee boxes with, no way to drain excess water. like timebomb waiting to happen ...

I have a tub of HC growing on GEX "Plant" soil outdoors too. The only different thing I do is that I do not "top up" the desaturated substrate (because the tub is transparent it is easy to tell). Daily misting is still administered onto the surface, though.

...The HC have mould growing on them, happen to alot of DSM using HC...

So the strands on mine, are mould, not fungi? Or is mould under the fungae family? If it is mould, may I know how to get rid of it?

...If DSM, maybe you can try giving some breathing holes? It would be good to offer a slightly larger tank shot as well...

I'm in the midst of organising some information about my setup; perhaps we can take this offline, & I'll be eager to supply the photos & data in a neater manner in the near-future? I'll remember your highlight about the "breathing holes".

...My recent HC attempt have fungi too , it was covered by cling warp and started just pior to hotter season...

Then may I know how did you rid the fungi off your HC?

...Btw: i grew sick by the time all my fault were found and flooded + co2 when HC started to spread.

May I know how many weeks of DSM implementation did you proceed with flooding? In addition, did your experience with DSM provided you with twice as much HC material than you seeded during the very beginning? Or is the gain (in terms of visible plant material, i.e. spreading) slightly lesser?

If it was an algae, the strands would be green since they basically are simple photosynthesizing plants...

Thank you for your elaboration; I may return with an even more colour-corrected photo, as this initial shot, wasn't fully corrected for the spot illumination of the torch I use to light the area. But the strands, as you mentioned, do not appear green to me.

& I feel so embarrassed to fail to recall that algae are actually capable of photosynthesis.

...It'll just find a way to get back to the surface and burying is no guarantee of killing it...

Agreed also, if it is fungi, burying it will only delay, not deny its propagation.

...Might as well remove the affected area, and replace with fresh soil...

But the thing is, how should I go about determining how wide the area to be replaced, is? Especially since they can distribute themselves by spores?

...No idea on whether the spores, if any, will affect your breathing.

If you do not see any response from me in the following few months...

Say in a 3 cm radius from the edge of the affected area. The whole section should be removed and replaced. If you see the fungi again, do the same thing. The filaments just spread all over the place so it's best to work fast. I had a small container of peat moss over-run with this thing.
