Cyano or coralline?

[rueric]

Can someone help me id this algae on my glass?
the pink is most likely coralline but the red/purple may be cyano or corraline

if it was cyano, does it make sense that there is none of the red on my sand or my rocks?

Looks more like coralline to me!

Coraline imo, cyanobacteria will blow away if you blast it with a Turkey baster

Try and wipe it off. If it wipes of easily and slimy, it's cyano. If it flakes off and is hard to remove it coralline.

Looks like both.
The pink is coralline. The red might be cyano, does it blow off?
Coralline needs to be scraped off.

Light purple coralline.
Dark purple sure looks like Cyano, scrape a section off, if Cyano, it will just slide off the glass.

I have an algae scraper and it doesn’t scrape off easily. Would need to get a scraper with a blade to take off

Then that is coralline as well!
That, be a good thing IMM, indicates great water chemistry.

Too bad i'm going to have to reboot my tank due to a vermetid outbreak..
Going to give my bumbleesnails and urchin to see if it can help clear it out

An old credit card works too.
