Help with algae type

[nijat11]

Can someone please help me to identify the tyle of algae on glass. It is brown dots and very hard to scrape it.
Please see the attached photos

If you have glass (not acrylic) you can use a single-edged razor blade to whip these puppies off.

Hi all,

It is brown dots and very hard to scrape it .......... Yeah doing with razor but still very hard

Because of the colour it could conceivably be a Red Algae (something like <"Hildenbrandia">), but it is likely to be <"Green spot Algae"> (Choleochaete), these are calcified and difficult to remove. I just get a little bit of this (where sunlight strikes the corner of the tank in the spring), but it never persists with me.

Any ideas how to prevent calcifiction?

Not really, I'd guess that it is less prevalent in soft water. This might help, apparently they are used as model organisms, so there are culture details <"Coleochaete | Haseloff Lab:">
