any help would be appreciated!

If it doesn't rub/siphon off I would say it is coralline.

To me it looks like red slime with a coating of diatoms. but thats just my opinion :)

i agree with Wes, but also try the recommendation Seahorsedreams gave.
if it blows (or siphons) off, its not coraline

agree with everyone !! i gotta start getting here a little earlier !!

well ..looks like its CORALINE!....with some diatom, but its definately not cyano...isnt that from fish? cause idont have anylol

No red slime is pretty much from phosphates. I have also had undetectable phosphates but still had some slime. You can get slime from overfeeding, getting a new rock with slime and water that isnt R/O. Not all water can give you red slime but some city water will.

If you want pull the rock out and check the red stuff if its a film that seems like slime then its slime lol. if its like a paint on the rock then its coraline.. i would have to say the texture looks like slime

ohh..well i touched it with a glove on..and it didnt come off and i kinda scratched at it..so i think its just coraline with diatoms on it?

yea if it didnt move and you cant peal it off then i would say it coraline.. :)

i dont think its red slime.. if i were u, i check my parameters and go from there. keep us updated

Looks like deep red coraline with orange encrusting sponge.
