Weird strings on coral and rock. GSP NOT GROWING?

[Jack684523]

My tanks been cycled for about 2 weeks. My gsp isn’t opening and there’s red strings growing all over sand bed and rock I keep doing water changes and vacuuming them and they grow rite back. I feel like it gets on top of the corals too idk what it is and how to get rid of it.

That’s cyano, Perfectly normal for new tanks. You just have to wait it out and if possible increase flow. You should wait till after the ugly stage to get coral .
How long ago did you get the gsp ?? If you just got it they don’t grow instantly. It takes time

Is it normal that the gsp isn’t opening. Everyone says it’s the easiest to grow
