Unknown orange substance on glass

[Reef.Blue]

I’ve been having a problem lately with an orange-like substance on my glass that has been near impossible to scrape off. I’ve tried my magnetic algae glass scraper and also my other algae scraper with a razor, but to no avail. I tried researching what this was, but most of the people that had an unidentified orange substance in their tank was on their sand bed. Is this some type of algae? Diatoms? If anyone has a way to scrape this off please let me know. The pictures attached make it look more greenish, but it’s more orange in person. Thanks.

Looks like cyano and should be Easy to scrape off and sponge off. Reduce white light intensity a little and add some snails such as
Astrea
Trochus
Nerite
Nassarius

a few Caribbean blue leg hermits

I have a wide variety of snails but none of them seem like they make an effect.

Isn’t cyano usually more green? And thank you for the suggestions. It is also very hard to get off the glass

Hard to confirm on phone but cyano can be red-purple-orange- yelliw
If it’s calcareous, can then be either calcium precipitation or coralline
You can remove with edge of credit card or similar

The marine cyanobacteria I've encountered has either been maroon or teal in coloration. I think green marine cyanobacteria exists though.

I've had these tough spots appear on my glass as well, though I never though to identify them and simply used a lot of elbow grease and an algae scraper (frustratingly, though it doesn't grow nearly as fast as film algae). They might be diatoms growing on some tougher, encrusting algae, perhaps what is referred to as "green coralline," which is usually overtaken by pink/purple coralline over time. I never had snails eat them, though an urchin might be more successful.
