I posted previously but my picture sucked so i'm back with a ever so slightly better picture.

in short, these orange globs have been forming in the indoor pool i work at for a year now. they form almost entirely in and around the pool skimmers (the holes around the pool edge that let suck water into the filter) we drained the pool, acid washed the concrete, and replaced the entire filter and it's back.

I don't know if this is an algae, fungi or mold so if you recognize or have any suggestions as to what it may be, please lmk

Found in an active sludge sample.

My Asparagopsis taxiformis culture is balling up and dying off after moving it from a 250 mL flask to a 500 mL flask. I’ve tried increasing light levels, reducing movement caused by maybe excess bubbling, and now I’ve moved it back into a 250 mL flask… any suggestions to save it?

Hi folks! I sample a stream (five weeks/quarter) that is impaired for fecal coliform and the results for the first week of this cycle came back really high for one of our sites. We noticed what I presume to be algae that we hadn’t seen before. This week the number is a little lower, but still high compared to our other sites. I’ve included pictures of the algae. Any help with identification would be extremely helpful to get a better idea of what could of caused this. This is in the piedmont of North Carolina.

I work at an indoor pool, bromine chemicals only, sand filter. For the past year i've been plagued with this orange algae? at least i assume it's algae. it grows primarily out of the skimmer entrances (the holes on the poolside that let in water) and it grows down the wall in front of the skimmer entrances. from what i can tell, it is not yellow algae. it is very orange in color and it does not grow on the floor at all, only in gooey clumps on the high part of the pool wall. it forms in almost perfect circle of goop, and when it's touched it falls apart into pieces like peter parker in infinity wars. please if you know who this algae is let me know. we have drained and acid washed the entire pool already and it's BACK. we also replaced the filter and the sand in it. i was worried maybe it was residue from bodily oils/soaps but that tends to be white and all the way around the pool, not just the skimmers.

any information or theories are welcome thank

Hi so I have a cyanobacteria bloom in my freshwater tank so I tried removing some and got some on clothes and cloths. So I threw the dirty laundry in the washing machine and washed it with hot water and a lot of laundry soap. It still smells. How can I clean it so the clothes are safe ? Thanks !!!

Hi! Perhaps this is a dumb question, but I've been growing Spirulina in a small tank for a few weeks and it looks like the water is evaporating. Are there any special notes you guys have about adding water to the growing Culture to top it up?

I'm growing Spirulina in my studio and it's a very small tank, but Im curious about how much Carbon Dioxide/Particulate is in my room at any given moment and how much Oxygen is my growing algae producing. Does anyone know a simple way to measure that?

Hey y'all,

I’m currently based in Berlin and looking to dive into the algae biofuel industry, specifically by building a subscription-based vertical farming service that helps companies scale their biofuel production. Instead of producing biofuels myself, my goal is to lease vertical farming systems to biofuel companies, providing them with the infrastructure they need to lower their feedstock costs (which I know is a huge pain point).

I’m at the early stages and want to get some advice on a few key areas:

1.	Building the Team: What specialists should I hire? I’m thinking bioengineers, vertical farming experts, and software developers to manage the subscription model. Am I missing anyone crucial?
2.	Funding: I’m researching grants like Horizon Europe, but has anyone had experience securing similar grants for biofuels or sustainability projects? Any tips for success or specific grants I should be looking at?
3.	Technology: For those familiar with algae cultivation or vertical farming, what’s the current best tech for large-scale algae production? How feasible is this approach for scaling biofuel production?
4.	Market Validation: If you’ve worked in the biofuels space or helped businesses scale, how do you ensure a vertical farming solution like this would be in high demand? Are there specific sectors (e.g., transportation, aviation) that are most likely to benefit?
5.	Challenges: For those who’ve been in renewable energy startups or biofuel production, what are the biggest hurdles I should prepare for (both regulatory and operational)?

Any advice from entrepreneurs, algae biofuel specialists, or anyone with experience in vertical farming or renewable energy would be much appreciated as it feels pretty daunting but I'm sick of sitting on the sidelines.

Thanks so much!

Can anyone help me identify the black/brown stringy algae (assuming it’s even algae) that’s covering this rock at a jetty in NC?

Sorry I can’t get a close up pic. :(

We found globs of this gelatinous pinkish substance by our local pond. Google lenses said it was Hildenbrandia rivularis. Does anyone know for sure?

Wasn't here a few weeks ago now it's all over this part of the steam.

From a lab practice in college :) I was told this is a red algae

Hi Guys, I'm working on a Photobioreactor in NYC for my Senior project and I think I messed up the ratios in my growing medium for my Spirulina, so I'm struggling to figure out where to get more Live culture here in the US. Does anyone know anyone in NY or nearby who is willing to donate or sell me some?

The setup is temporary, she'll live in a bigger bowl with rocks but i think she's adorable as is :)

There's a bunch of small snails feeding off it and it doesn't seem to go away

This is in spots in my Gravel driveway I recently found little lesions on my dogs belly and I know like a month or two ago he was laying in the driveway where the spots were just wondering if they're harmful to my dog and they cause these things on my dogs belly who already has allergies

Hello,i was looking at this algae through my microscope and all i know about her is that it has no flagela and has a darker spot in the middle.What species it could be?

Hi guys, newbie here,

thanks a lot for your input in my previous post, I managed to do DM for my algae, but I still need help from you guys to identify this correctly, thanks before :)

Hello everyone, I am a master's student who has recently developed an interest in microalgae, and I would like to ask for your advice regarding an issue I am facing.

My Chlamydomonas reinhardtii strain CC-4414 is growing abnormally in TAP (Tris-Acetate-Phosphate) medium, cultured in a shaker at 125 rpm, incubated at 25°C under limited light (dark) conditions with a 12:12 hr light/dark cycle. The picture I showed is of C. reinhardtii incubated for 7 days. Has anyone ever encountered this problem before?
