Its a macroalae known as foraminifera and is very responsive to red lighting which promotes algae

So cut the red light? Is it ok in the sump?

Looks like vermetid snails to me.

Are they good or bad?

They likely are vermatid snails. They reproduce quickly and can take over.

My apology- Got off the phone screen and looked on my full computer screen and vermetids indeed and these are out of control. Your best bet for erradication will be a pair of bumble Bee snails which will consume them one by one. You can if possible break off many with a plier at the Very bottom base - do not snap in the middle as they will simply regenerate.

So there down in the sump,Is it possible the could get in the display tank? Or should I just let them be in the sump?
So far they are only on one rock which is no problem I'll just take it out.
