The algae hooks that i used to play with during childhood. This is a side view of the concrete stone that i kept on top of my water tank as weight. This morning i found my childhood hooks have grown on them.

Playing with rheinburg illumination and a 40x water immersion objective.
Unfortunately I have not been able to find a water immersion objective that is also plan (flat-field corrected) !! What gives!

I had seen this happen before, l keep a 4ft x 2ft plastic tray 2 inches deep of water on a shelf in the greenhouse, I put plants that are in trays or pots to soak water up from the bottom. In the warmth of the sun Algae forms as a skin on top of the water.

Because of their calcified structure, coralline algae have a number of economic uses. The collection of unattached corallines (maërl) for use as soil conditioners dates to the 18th century. This is particularly significant in Britain and France, where more than 300,000 tonnes of Phymatolithon calcareum (Pallas) Adey & McKinnin and Lithothamnion corallioides are dredged annually. Some harvesting of maërl beds that span several thousand kilometres off the coast of Brazil takes place. These beds contain as-yet undetermined species belonging to the genera Lithothamnion and Lithophyllum. Maërl is also used as a food additive for cattle and pigs, as well as in the filtration of acidic drinking water.
The earliest use of corallines in medicine involved the preparation of a vermifuge from ground geniculate corallines of the genera Corallina and Jania. This use stopped towards the end of the 18th century. Medical science now uses corallines in the preparation of dental bone implants. The cell fusions provide the matrix for the regeneration of bone tissue.
Since coralline algae contain calcium carbonate, they fossilize fairly well. They are particularly significant as stratigraphic markers in petroleum geology. Coralline rock also functions as building stones, with the best examples being in Vienna, Austria.

Gold Algae Eater
Gyrinocheilos aymonieri
This slender algae eater has a silver underbelly with a bright yellow/gold back. A horizontal line that is patterned runs along the side. The Gold Algae Eater comes from Northern India. It is usually kept in tanks for the purpose of keeping algae under control.
The main source of food is algae on plants, rocks, glass, and driftwood. Algae based wafers should be provided if there is a lack of algae.
