Not sure if these Algae are good or bad

[flex13]

Hello

Just passed the diatom stage and now i am growing all kinds of cool algae. Are they ok or should I start removing them? sorry for the quality of the pics not sure how to take pics with blue light

What are these white soft tube looking?

These round ones?

and this one?

The first ones look like Bryozoans or Sponges sp.: filter feeders a good thing.
The second and third are Sponges sp.: filter feeders also a good thing.
They will go away by themselves as the nutrients they are feeding upon decrease.
Here's a great link to with pictures of all sorts of critters and creatures, some good some bad: https://www.lionfishlair.com/hitchhikers-guide/

I knew the picture will be hard to tell, I am going to pull them out and take a picture.

They are all macro algae..

1. The tube is a calcareous algae Neomeris Sp. which most have a hard time growing but for some other it grows well. Requires good alk and calcium levels.

2. The spiral stuff is a brown algae Padina Sp. This dies off after a while, not easy to keep. I wish it did it is a unique algae.

3. The ones that are split on the end and are kind of iridescence are Dictyota Sp. and some time are bad and has the possibility to be a nuisance but not always, i think it depends on the species.

I see you also have some other red algae mixed in there and some calcareous algae too. None of those are ever a issue. Looks like this is aquacultured Caribbean rock if I were to guess.


Personally I like macros in a tank, especially Neomeris and halimeda. Some of those are natural on a reef.
The one I would keep an eye on is the dictyota .

In this picture you can see Neomeris in one of my tanks.

You are the man . After the diatom died off all these macro algae took off. Ill leave them alone but pull some of the Dictyota Sp. its everywhere. Not sure where the rock came from I bought from my local Reef store here in Miami. When I bought the rock it didn't have any macro algae but allot of good and some bad hitchhikers.. Got ride of all the bad ones that I can tell but I have one left I cant get Polychaete - Eunice freaky looking LOL

Anyways thank you for your help.
