Please Identify for a Newbie

[ReeferGladness]

I have now had my 90Gal Tank setup for about about 4 months. I'm starting to see some new growth in my display as well as my refugium, but I'm too new to the hobby to be able to identify them. Any help would be appreciated!

This first thing I found was stuck to the grate of my return pump. Its red and bubbly, but its got the texture of plastic or rubber. Bubble algae maybe? Is this bad?

Next, I am starting to see this greenish/yellow algae show up on my overflows and back glass. I haven't noticed any on the sand or rock. Can anyone identify? Is this good or bad? If I should remove, how should I do so?

Lastly, I am noticing this purple stuff attached to my chaeto in the refugium. I think it might just be coraline algae. As you can tell from the second picture, I am starting to get a lot of this purple growth on the walls of my fuge. It all looks the same to me. Any ideas? Good? Bad?

the first pic looks like valonia (bubble algae) it is considered a pest by many because if you pop it it releases spores into the tank and you can have a problem very quickly.

I'm not sure about the middle pic but I think the last one is cyano in your chaeto but i'm not sure

The very last pic looks like Coraline algae to me ?

Agree with both.

ditto. The yellow stuff: probably sponge. Top, valonia, or bubble algae: hard to get rid of, few things eat it; cyanobacteria in the cheato. Coralline on the glass. Not sure what the dark pic is focussing on or what the scale is. Could just be detritus sticking to algae. Or do you mean the white spots, which could be snails, sponge, or an oncoming asteroid... We need scale on that one.

What you probably actually would like to hear: all normal stuff for a tank. Cyano in a fuge, no problem, except you need your skimmer in better form---make sure it's going hard.

I had a pretty bad case of red valonia algae, I hate that stuff.
I got a few emerald crabs and thought they weren't eating it, then I noticed that they are all popped. They do pop the algae which spreads it around but mine are keeping up with the new bubbles, and now I don't have a problem anymore. I thought the emerald crabs were a loss cause, but it just took some time for them to get on top of the new growth.

Thanks for all the responses. I have an emerald crab in my display tank, but found the bubble in my sump. Hopefully I won't have an outbreak of it in my display.

Anyone think I should worry about the yellowish stuff growing on the overflow?

The dark out of focus picture is that same yellowish stuff growing on my back glass. There are little spots of it about the size of a quarter.

The yellow stuff is probably a sponge and is beneficial
