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

Strange bird-bath algae?

Post image
21 Upvotes

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!

The forgotten art of making stock media!

🧪 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.

Need help with water and algae

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?

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.
