Something on my zoas help:(

[Kawasaki213]

There's like blue slime on the base and long strings on it what should I do?

Looks to be a sponge (the blue) based on what I can see in pic. Can't really make out any "strings" to be certain on ID.

Sponge is harmless filter feeder

Sponge if bothers them exposure to air kills the sponge. Dip in coral rx or something rinse and put back into tank.

See like the hairy stuff under the heads? Should I get rid of the blue sponge then or just leave it?

Better pic, but I'm unsure of ID. Keep an eye on the zoas. They look happy to me, but if start to stress or lack of opening, it may be a good idea to remove. I don't see any cause for concern (based on the blue, the other I can't Id so I'm unsure) hth
