Hydroids or cyano?

[waldemar]

Good morning everyone! My tank is going through the ugly phases diatoms came and went green algae has just about stopped. Now I’m getting small pinkish red clumps popping up. I’m assuming it’s cyano but wanted a second opinion. I would rather not let hydroids take hold if I can help it. Thanks!

Pics under white lights would greatly help with answering this question. But, it does sound like cyano...but also possibly coraline algae can be pinkish red sometimes.
