Zoas and red algae?

New "algae" question.
In the middle of my largest Zoa colony, I have something that looks like rust red algae covering 5 polyps. It's obviously irritating because those 5 are closed shut.

Does this look like red slime that I can treat? Or something else?

Heres another image...same stuff on Halimeda

 

Shaky hands. Here's another pic

 

I was gonna say the same thing lol

 

That was effective! Thank you.

 

It worked really well!!

 

I have a red turkey baster for coral dip...and I bought a couple of the really long tube acrylic kinds for feeding. I like the thinner tube. I felt like I was force feeding the Duncan's the one time I used the baster. Covered the poor guys. And my tank looked like a snow globe. Shrimp was happy though. I have better control with the long skinny tubes and smaller pump.

 

Do you guys use a sand vacuum and if so...how often?

 

I don't like to vacuum sand unless specifically sucking up cyano. The sand bed in your reef tank will contain lots of good micro organisms as well as worms, stars, and pods.

Cyano is common in newer tanks. Chemi clean works well. Sometimes too, it's a symptom of too little flow. That is, the bacteria are less successful at colonizing medium/strong flow areas.
