If you can get a brighter pic it may help, those are almost too dark to see anything.

congratulations thats cyano! dont use tap water for top offs and check your phosphate level. If it is cyano cut your light period in half.

Are you sure the red one is slime algae?

i got informed and i only leave 12 hrds of light a day... instead of 15-18, i installed a timer.

If you can suck the red stuff off the rock with airline tubing or a turkey baster, it most likely is cyano....coralline is usually a hard incrusting algae that won't just rub off...it usually takes some elbow grease. You will love it until you have to scrape it off the front of your glass!

The purple rock off to the right in the first pic is definately coralline but the larger portion of the rock does look as though it could be either cyano or possible a form of velvety coralline. Easiest way to determine it as two11devan said is get a turkey baster and try to "blow" it off the rock. If it stays put, it's most likley not cyano...

The second pic is very hard to make out but it could be a type of turf, brush, bryopsis or similar. Can you post a better pic?

Cheers
