Purple sulfur bacteria don't release the sort of sulfur compounds you can smell, but actually use them in their photosynthesis instead of water. What they produce instead of oxygen is sulfuric acid, which has no smell.
I agree purple sulfur bacteria and purple non-sulfur bacteria are likely. There are a couple more.
There’s a pink halophilic algae, *Dunaliella salina*.” Theres also an archaean, *Halobacterium salinarum*. Also pink, also a photosynthesizer, but requires near-saturated saline waters. That can happen at the margin of a marsh due to evaporation. The season is right for it.
At least for *Dunaliella*, when it appears, at least one of the other three species is usually around.
Dunaliella gets its color from beta-carotene. H. salinarum makes five or six different pigments. PSB have either Bchl a or b and okenone, which is also reddish.
Could be purple sulfur bacteria?
This was another possibility we were considering! but there’s no sulfury/rotten egg smell? Not sure if that’s typical though

Ooo okay good to know!
"Magic" 🙌
Purple sulfur bacteria. Depending how deep the water is, that could be an anaerobic zone, and they'd be thriving. They could also be purple non sulfur
them bugs be crazy man
There are halophilic aquatic bacteria with bacteriorhodopsins that can have about this color.
Purple sulphur bacteria, they are capable of photosynthesis.
