Red or Pink Algae

[Jetmart]

Tank is 6 weeks old and all parameters are great. Had some diatom & green algae that the CUC took care of.
Now just starting to see some pink or red algae on the profile of the sand bed just where it touches the glass. There is none on the surface of the sand. Any ideas?

For a tank that's only 6 weeks old, Cyanobacteria came to mind first. Can you describe what your seeing a little?

This is what I am seeing.

Looks like cyano to me

When I bought my Liverock from a LFS it was from a established tank and unknown to me at the time some of the rock
had Cyno on it and when I put the rock in my tank it went crazy. I used a turkey baster and a fine net to remove as much as I could.
within a week it was showing up again. so I used Chemiclean and it got rid of it and hasn't returned. didn't bother any of the coral or inverts either.

Cyanobacteria is my guess also. Here's a read about it:

I've delt with cyanobacteria a couple of times now...I had best results treating with Chemi-clean.
Followed directions EXACTLY as directed & had no noticed bad side effects.
It is best to understand and FIX what the causing problem is however. Mine was lack of water flow.
I added powerheads to my refugium making sure all areas had good water movement.
I resisted the use of Chemi-Clean for a long time but I don't regret using it.
Opinions on use of "chemicals" greatly varies...just so understand that!
If you go the Chemi-Clean route: FOLLOW the DIRECTIONS.

That is such a small amount in a new tank I wouldn't fret about it just yet.

I agree with Mike Johnson. Try to manually remove as much as you can by vacuuming your sand really well. Do frequent water changes and make sure your lighting is limited (most people say 8 hrs a day or less) and increasing your flow.

How big is your tank?

What if there is a little in your refugum is it ok to be there

Cyanobacteria is pretty common in almost everyone's tank from time to time, it's usually associated with over feeding in mine, it not really hurting anything, and can be defeated pretty easily by feeding less, vacuuming sand, increasing flow & decreasing your light cycle for a few days.

Have you ever considered building one of these? These work great:
