looks like cyano. it can become a real nuisance once it gets out of control. it could grow on almost anything, LRs, sand, pumps, glass. a real eyesore, but this is, IMO, normal for a new tank with all the biological imbalance in it. you can opt to siphon it out but as long as there are excess nutrients, cyano will most likely fluorish again. my suggestion is to go easy on adding livestock (maybe you should opt to stop adding anything until the cyano disappears) and consistency in your husbandry routines. HTH!
