Bubbles on live rock and diatoms??

[Luka]

I will get the hanna so these diatoms just come back with the light after stiring up the sand last night they are back. I think they might be brown hair algae this is the longest one I've seen. Hard to see it but it's that little brown strand let me know what u guys think.

Okay so I did some research and it seems to be cyano anyone agree?

Looks like diatoms to me, my tank is going through them now as well. My tank is about a month old. I plan to just let mine pass. I added 3 snails and 2 hermits to help clean up a bit but that's all. Keep up on water changes and let it pass. I have a 20g long tank by the way.

Some of my Zoas closed up before it was 2-3 now it's triple that might be the pump I added

This isn't cyano but just a regular diatom bloom, the bubbles you see come at the end of the day and is a result from the photosynthesis that takes place due to your lights.
Need to know your Po4 and No3 before you can take action.
A 20% water change always is good and keeps it at bay.
Turn of your lights for a day and see if they are gone, or you can do three days of total darkness but I don't think you have a major problem on your hand here.
Let us know when you get some test results in.

Agree with diesel. Looks to be diatoms. Take a look at your tank before the lights come on for the day. More than likely the sand bed will look clean, if so its almost definitly diatoms. Diatoms are caused by silicates. Try to get a silicate test kit and see what it says.

Okay will do I will order some test kits for tomorrow thanks guys, really appreciate the help and guidance.

The tank looks clean in the morning just a little bit of brownish coloring

Thanks for letting us know and that points out that you are going through a diatom cycling again.

Watch you feeding schedule, adjust your light schedule an extra WC can't hurt either and in a few days you should be good.
If for some reason it won't you can always do a three day of total darkness, to do so you have to cover you whole tank that no daylight will come in your tank either.

Update I vacuumed my sand and did a big 5 gallon water change (tanks a 15 gallon) the algae came back the next day. But more of my Zoas opened up. the "diatoms" are still growing string looking algae. I have some Dino looking things in their right now. It's freaking me out. It might be hair algae with bubble at the tip anyway to tell? You can also see the diatoms growing under the sand is that normal?

 

[Diesel]

Nah it won't grow under your sand, it's because it's against your glass as it looks like under your sand.
Keep up the good work as it will soon stop.
You might dial back your photo period a few hours.
Less light is less diatom and your tank will balance it out.

 

[Luka]

And the Dino looking things? How much less hours of light should there be? I have it on automatic sunrise/sunset rises around 8:15 am sets around 6:15 pm then moon light for 4 hrs

Starting to see some red cyano on some rocks and Areas with high flow there is no diatoms. Also looks like they are growing on my Zoas.
