Like a blue green color. Just got past the diatom phase in my new 75g a few days ago and already this nasty crap is popping up. Any ideas?

May just be part of the ugly stage?

what’s your nitrates and phosphates at?

is it just on the rocks?

hopefully someone else can chime in
It very well could be a part of the ugly stage, I’m sure it is, I also have gha and I think a small amount of cyano, kind of unsure it could be coralline starting I did seed 2 large bottles during my cycle so it’s a unlikely possibility.
it is only on the rocks so far, I just noticed it today, it’s definitely new I scope out my tank constantly to keep a close eye on the uglies as they come n go, I had 2 waves of diatoms and now some gha growing, will be adding a blenny soon once I get a chance to go to the lfs.
my nitrates as of the 4th around 10, phosphates have dropped to .25 from .5 on may 21. I added a bag of chemipure to help with the phosphates and silicates and it actually got rid of the diatoms rather quickly, the diatoms lasted around 2 weeks.
 
Looks like cyanobacteria aka red slime aka blue green algae even though it comes in all colors. If there’s not too much just siphon it out.
Just a few spots on the rocks, actually pretty hard to see and get to, I will do a small water change tomorrow just to syphon it out, will likely have to move some rocks to get to it.

Use a turkey baster to blow it off the rocks and suck it up during your water change
 
Also maybe 8 red hermits, and a cleaner shrimp but that’s not for algae.
 
I did recently lose two fish (a fire fish and a watchman goby) due to a major alkalinity drop to 4.5 with my newbie self not paying attention. Now I just have two clowns and the situation has been good for about a week at 8.4 ph and holding steady 7-8 alk, when it hits seven I dose back to 8, but I don’t see how that would make algae appear.
 
If you can baste it off and suck it out, fine. Otherwise ignore it. It is about to be replaced by something else. It will certainly be red. Or brown. Maybe green. But probably brown. And fuzzy. Or maybe furry. Wiry is also a possibility.

It is all good; just part of a maturing biome. For giggles (and learning) I will suggest you get a microscope so you can put each of these uglies under it and get an ID. You don't need to do anything about it other than discover how your tank is maturing.

Note: fish don't care about alkalinity. Maybe your salinity is moving?

I should just let this do it’s thing like the diatoms? Will each phase of the uglies go away on their own or should I be treating for each one? I kinda let diatoms do it’s thing till it started what I thought killing my corals but turns out that was my Alk bc now I have 3 baby Duncan heads forming and my zoa took off running with like 5 baby heads. I had a post of here about it trying to figure out what killed my two gobies but I never got a real answer turned into my Alk being dangerously low and being all about that. I assumed the Alk was what killed the fish. My salinity is steady 1.025-1.026 I am slowly working on bringing it down to 1.023 bc i have such a high amount of evaporation.

I have been thinking about getting some cheap microscope just to see what the algae’s look like up close. Science is fun.

I got one to ID dinoflagellates (don't go there) but my son and I use it all the time now for viewing all the different bugs, slimes, algae and miscellaneous. Use you phone to shoot pics/video through the eyepiece.

Some examples of what are or will be in your tank. All part of the fun.

Sorry. Some of those files are kinda big.

That’s okay haha, the only one that loaded was the first one, that’s the Dino I take it? That’s pretty cool looking. I’d love to get up close n personal with some coral n a microscope. Prolly looks pretty sweet, and definitely some bugs if I could ever find any. Only thing I’ve seen so far in my tank is the copepods n amphiphods buts it’s still a new tank, only 2 1/2 months old post cycle.

For the first 12-18 months I suggest staying focused only on the big things and not the biome noise:
a) Temperature
b) Salinity
c) Food in / waste out in roughly equal proportion. 20% WC every two weeks is good. Baste rocks and stir sand.

Some months in, refining your water testing process is good. I test ALK, NO3 and PO4 every week. Salifert, NYOS and Hanna respectively. Sometimes a little more often if things are really changing. WCs cover the rest.

I was going with the theory of not chasing numbers, since my nose dive into the Alk I have been testing every other day ph and Alk just since then. I was testing ph, nitrate phosphate Alk every other week after my 20% water change. I have decided I’ll be testing every other day probably for the next few weeks till I can figure out exactly how much Alk is consumed n how often to dose, but eventually I’ll probably start testing all the basics every week. My temp I really haven’t been paying attention to but I do have 2-3 degree difference between day and night. Which I think seems like a lot and have been thinking about maybe getting a chiller.
