Need help with algae ID

[Chris H Reef]

Hey all,

Can anyone help me ID this algae?

My tank has been running for about 3.5 months. I had only seen a little algae until I did a water change a few days ago (10%). It’s the first water change I have done but recently got the corals so wanted to make sure the water was clean for them.

The corals are not doing as well as before either and have receded quite a bit.

Any idea what might have happened?

Amonia: 0
Nitrite: 0
Nitrate: 10
Sal: 1.025
Alk: 7
Ph: 8.2

Looks like diatoms. Just let the process go.

Thank you! That’s what I was thinking too.

So just ride it out and don’t change anything?

Will it affect my fish? I’ve been slowly stocking every 2 weeks or so. Can I continue stocking?

They'll go away pretty quick
