help to identify algae

[Miranda]

Hi I'm from Brazil I need help to identify this algae has brown color in the microscope does not move

Thanks.

brown color with bubbles on the top means it's Dino.

Start Dino X treatment for 40 days and you will be ok. Then control nutrients so it doesn't come back.

Really ? under the microscope they don’t move and have a round shape

Dinoflagellates are often round. Is this a well plate or did you use a coverslip? Coverslips and prolonged exposure to heat (like from a light element) can reduce movement to nothing. Try getting a less concentrated sample at tank temperature in a large drop of water.

Just my suggestions.... Good luck!

I just collected a sample and put it under the microscope it doesn't move, I've had dinoflagerates in the past and it moved

i will try a 3 day blackout

i'm worried is growing very fast

From your pictures and description I don’t think there is enough evidence for a positive identification. A clearer microscope picture with some idea of scale would be helpful.

some pictures under the microscope

Thanks

Yes but it looks very same to Dino I have faced long time. I used Dino X and it vanished

The microscope pics are too low mag to make a definite identification. Can you increase the mag and clarity?

Grab a clump of the stuff from the sand and then focus the microscope on the outer edges of that clump. This gives less congestion and easier viewing of any cells and more room for them to move.

I am far from an expert. I have just started using a microscope and am still trying to piece together what I have observed. I just want to show why I think you need more detail to determine what you have.

Fig 1 shows cyano bacteria. I did not take a macro picture. It forms mats on the sand similar to your picture

Fig 2 shows a macro picture of my aquarium glass.

Fig 3 is a microscope image from the aquarium glass. It has a large percentage of dinos. They were moving fast when first placed on the slide. I don't know what the larger brown algae is. Maybe dinos clumped together.

Fig 4 is another microscope image from the aquarium glass. Here the green dots are not dinos or cyano. It is a type of green algae the clean up crew loves to eat.

So, 3 type of algae and bacteria looking like dots.

the best I can 100x

yes it seems a lot, i will try the blackout of 3 days
if it doesn't work I'll try red slime
