Anyone seen this before, Sorry for the poor quality photo.
Is it really a wall of BBA algae?

I find them quite interesting, I'm not sure I want to grow anything intentionally in my tank.
I must confess I had to Google the difference between a moss and a algae.
Looks like algae are far simpler structures.
Classification
Moss is classed as a bryophyte -- a type of tiny plant suited to moist but land-based conditions. All bryophytes are believed to have evolved from tiny water plants. In fact, according to Karl Danneberger at Ohio State University, moss developed directly from algae around 350 million years ago. However, algae form a scientific classification of their own. Algae are mainly single-celled plants collected together in growing clusters.
Appearance
In general, moss looks fibrous, feathered or latticed when viewed up close. Carpets of moss are springy to the touch. When germinating, moss puts up thin stems sometimes with leaves on top and reproductive spores.
There isn't really a group of organisms called "Algae", it is a colloquial term to cover nearly anything that photosynthesises, but isn't a higher plant (in this case including mosses and ferns). Blue-green Algae are really bacteria ("Cyanobacteria") and the Brown algae ("Phaeophyceae") belong to an <"entirely different kingdom"> to the Red & Green Algae and all other "plants" .I must confess I had to Google the difference between a moss and a algae.
Quite possibly, there is very little fossil record for early plants, but <"shortly after the invasion of the land"> plants were already <"quite complex">.Sounds like algae just started joining together to for filaments so it could break though the waters surface move to damp land and was rewarded with an abundant supply of CO2

Platysulcidae is a monotypic family of heterokonts that was recently discovered to be the earliest diverging lineage of the Heterokont phylogenetic tree.[1]
There are a number of different names for these groupings, a lot of it is to do with <"cladistics">.to finaly get redirected to the <"Chromista"> kingdom
In the case of the algae it is back to the <"DNA analysis"> that has found all the different nitrifying organisms, once you start looking at "algae" you find a whole lot more genetic diversity than was apparent from morphological or biochemical analysis.Darn large kindom and seeing the dates of the latest discoveries from 2017 they still are finding new species.
