Coralline

[Percula]

We have a lot of Coralline in our 65 gallon which has been set up for four months now. That being said, I am wondering if it is ok for it to be "growing" on the sand?

Looking forward to your thoughts.

Coralline doesn't usually grow on the sand. Can you post a picture? More likely, it is diatoms or cyanobacteria (red slime).

Will try to post a picture, but if it is red slime, what do we have to do about it?

 

[Bifferwine]

If it's a new tank, red slime is really common and unavoidable. You can increase flow in the area where it's building up, and you can improve your water quality. There really isn't anything that will eat it, but sucking out as much as you can with a turkey baster also helps.

In time it will dissipate.
