A rare and unusual specimen of algae preserved in clear chalcedony. Originally it would have been growing in silica-rich run-off from geothermal hot springs. Kaueranga Valley, Thames

On the site of a former mill, a few minutes from the town centre, the River Irwell runs through the park, as does the East Lancashire Railway which has a station there.

My municipality installed a storm water drainage system in the past year and one of the storm pipes empties into a little valley in the neighbouring lot.
Looking from above, it looks like a horrible painting and it was this thought that guided the post-processing.

My tank was doing so good..... then the brush algae came. I had to trim the plants all the time just to keep the algae down. It's so gross looking. It looks like pubes. Anyone know a cure for it for sure?
Green algae is Hydrodictyon, the water net. It is a related to Pediastrum, but it forms a bag-shaped colony. Like Pediastrum each individual cell can develop into a new colony. You can imagine that since the colony contains thousands of cells Hydrodictyon can reproduce very rapidly. And unlike Pediastrum, Hydrodictyon can grow large, almost 30 cm. in length. Blooms of Hydrodictyon can be a real problem for water treatment plants.
