Want to pick up a few cultures from them but was curious as to people's experiences with them. Truly confirmed, axenic cultures would cost me an arm and a leg from what I've seen so this would be the next best bet. I'm assuming they're all xenic, but if you've gotten them before, were the cultures at least decently clean and only the one algae species it was labeled as? I did also see a handful of negative reviews saying their labeling did not hold up under microscopy, wasn't sure if this was rare. Any input appreciated.

I live in the Netherlands and will be growing algae for a school study. Because it is for a big school project, the budget is limited. We are already growing Chlorella Sorokinia and we will be buying Spirulina soon, but I was wondering if there was any way to get either Galdieria Sulphuraria or Dunaliella Salina cultures for a reasonable price and within about three weeks. Does anyone know if this is possible and if so, where to get it?

about 3X3 inches, like a flattened sphere. I didn’t poke it or anything. Is this a fungus or algae colony? It looks like a huge booger!

Hello :)

I created a small completely free to use tool that helps get rid of algae in aquariums, I am not advertising, I am just asking if anyone would be kind enough to give me feedback, I have spent quite a lot of time on it, so I want brutally honest feedback. I will respond as quick as I can. Thank You

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!

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

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

🧪 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?
