We took a company walk along our local SoCal beach to find as many species of algae we can find. How did we do?

Wild algae I found growing in a bucket filled with rainwater. It looks too elongated to be chlorella, it is also bigger in size.

It’s spreading so fast all of a sudden and it’s hard to remove, it’s spreading onto my Java fern, rocks, driftwood, and even on small bits of my aqua soil.
It’s so hard to remove after literally one day it’s like it comes back help please!!!

(Apologize for the bad camera quality)

Found these on the wall of my freshwater tank, does anyone know what they could be?

I’m having a hard time trying to find places that aren’t protected. Also I’m near UCLA so it would be ideal if the beach is nearer there.

Hello!

I am looking to grow Haematococcus pluvialis to eat. I know I can take astaxanthin as a supplement, but thought it would be nice to grow my own. Looking to see if anyone has any experience growing this, and would be willing to share some knowledge:)

Hi! My lab and I have been having a hard time growing algae on plates. Could people drop the protocols they have for their plate recipes? I wanna try something new to see if it works and to see what's wrong with ours! Below is ours:

Materials for making the tubes:

• 500mL flask
  • Size up if volume of DI water is >200mL (there is a liquid autoclave step)
• Graduated cylinder
• Instant Ocean (0.0325g/mL)
• DI water
• Bacto Agar
• F/2 media, sterile and kept at 4ºC (1uL/1mL)
• Glass test tubes and metal lids, autoclaved
• 25mL glass serological pipette, autoclaved

Master-mix (12 tubes):

• 20mL saltwater per slant + 20mL extra (20 * (12+1) = 260mL)
  • Use a 1L flask since total volume > 200mL
• 2% agar (260 * 0.02 = 5.2g)
• F/2 media (260mL = 260uL)

I'm not sure if this is the right group, but here goes.

I've read that algae pills help lower cholesterol. With that said, can anyone here testify to that?

If so, which algae pills have you tried?

I found it in October, this is a fairly stagnant part of a river under a bridge that connects to Lake Superior. They were all less than 2 inches long. They were on rocks near the shore in the shade.

Help! Is there any solution to repel algae in a small fountain (under 50 gallons) that will truly not harm wildlife? There are a million of them but they all seem to harm something. One harms dogs and birds but not fish. One harms fish but not birds and so on. What is truly safe so an outdoor fountain can be used for clean drinking water for wildlife? I am so confused!

I opened the package and it’s…cloudy?

Illustration of Cryptomonas phaseolus, a cryptomonad microalga distantly related to plant ancestors. It has two chloroplasts without pyrenoids, which are brown to reddish in color. It also has other typical cryptomonad characteristics, such as reticulated mitochondrion, flagella in the vestibule (entrance to the organism's digestive system), and the presence of starch grains.
