Sand stuff???

[rainetheiceman]

I have multi coloured stuff growing on my sand. I'm assuming algae but not sure??? Good/bad? keep/clean? If clean, how??

One Of the many different cycles, just let it be.

How long has the tank been up and running? More Stats would be helpful as well.
Any new rock? Fish? etc..

That is cyanobacteria. Assuming your tank is real new, this could be very normal. Here are some Cyanobacteria links.

Tank's very new, only about 4 months

It's probably just normal new tank issues.
