Algae often occurs in pools that are not cleaned properly and whose chlorine balance has dropped. Maintainingfree chlorine levelsbetween 1 and 3 parts per million (ppm) will prevent the growth of algae. Usually green algae appears, but white algae sometimes does, followed by a pink algae that ...
In the almost empty train car of the new Keio line, I found that the perfume, which I had applied quite a lot of (it is an extrait) put me in a state of peculiar tranquillity. In many ways not me – I do like marine fragrances sometimes, but they are more what you might call m...
