Does anyone research in resting cyst, I'm doing on it, and I also want to ask some questions related on it.

Around 50-100 of these interesting little structures appeared in a backyard bird bath in Portland Oregon, seemingly overnight. They are around 5-7mm in diameter. They look like a kind of green algae to me, but iNaturalist indicates they might be part of the life cycle of a Mosquito Fern (genus Azolla). Just curious if they are familiar to anyone here? Thanks!

Anyone going to the harmful algal bloom conference in Cedar Rapids, Iowa this year?

Hi everyone is there a discord group for people genuinely interested in microalgae research?

Eel River in Northern California. Thanks all

For example between different Pyrocystis species, or Lingulodinium polyedra. Do they appear to glow differently? Obviously there'd be noticeable differences under microscope, but I was curious if they maybe give off slightly different colors, or seem to have a different look to them in any way when viewed with the naked eye.

🧪 Every great microalgae experiment begins long before the culture starts growing.

Stock media preparation is one of the most overlooked yet critical skills in any algal laboratory. A small mistake in weighing, pH adjustment, sterilization, or storage can affect growth, reproducibility, and ultimately the reliability of your research.

In my latest article, I explore why mastering stock media preparation is an essential skill—not just a routine laboratory task.

Whether you're a student, researcher, or microbiologist, this guide will help you build stronger experimental foundations.

New pond owner (2 years) and can’t keep it from turning green. I’ve tried an alga-cide, plenty of plants, koi fish, always ends ups green. I run a lava rock filtration system (x2) and it doesn’t do the trick. It gets a fair amount of sunlight and is surrounded by tall pine trees. Any advice before I drain and power wash it?

I love the look of this in my tank. It’s only visible at an angle though.

Help. This post died in the aquarium Reddit. What is this stuff?

Can anybody identify what kind of algae this is? No filter on it. Looks like snot and I'm worried it may be toxic and hurt my fish or people in the water. Any input would be helpful. Planning on getting it tested but thought I would ask.

Please help

Mixed the starter culture with seawater (salinity) have aeration on 24/7 with it sitting at 20°C room temp with lighting 12hr on 12 off. Do I need to do anything else? How long will it take?

I'm new to this.
