can anyone help identify this algae?

Hi all,

New to the forum here, and really hoping if someone can help me out with identifying some algae that I have. I’m not sure if I’ve got diatoms here or some sort of hair algae. I *think* I’ve been reading up enough to know how to get rid of it if it’s brown hair algae (water changes, excel, lower light, phosphates etc) but if they are diatoms, seems like I have to dose with more beneficial bacteria?

Any help or suggestions would be greatly appreciated.

Thanks

This is not blackbeard algae or diatom algae. Blackbeard is dense and short typically, and very very dark. Diatoms tend to be a dark coating on only surfaces in patches. Honestly it's hard to tell from your photos but it kinda looks like staghorn but youd have to look closely to photos of staghorn and compare it to your algae to find out for yourself.

Once confirmed as staghorn, remove as much of it as you can then correct any issues that caused it and keep removing it as it grows until you win.

Staghorn is caused by low water circulation, low co2 and too much light.

Thanks so much for the feedback! So whether Staghorn or Rhizoclonium, my issue is most likely the lack of CO2.... looks like I'll have to do a DIY CO2 setup which I was hoping to avoid, will post progress in a week or so.

CO2 will help your plants but I am thinking its not gonna be the answer to your problems with this algae. Physically remove as much as you can, do some water changes, take a look at your lighting (time, distance, intensity). I wouldnt recommend jumping into the CO2 thing if its not something you want to do.

Not sure if you have used DIY C02 before, but word of advice is to keep it as consistent as possible. Letting it run out is the biggest problem and can cause issues. Maybe two bottles then space apart a week for more consistency. That's what I did years ago and worked well

Staghorn and Rhizoclonium are quite easy to differentiate in person or with a clear photo. Just hard to see in your photos for me.
