Excerpt from Transactions, Vol. 17: July, 1887
Perhaps there is even a formation of bioxide of hydrogen, which would explain this coefficient of solubility as being so much greater than that admitted by chemists. However that may be, for me the fact is now incontestable that to establish in an aquarium a hygienic medium suitable for the life of aquatic animals, an abundant vegetation must there be developed, which should frequently undergo the action of solar radiation.
Most successful aquaria are constructed with what may be termed closed circuits, not drawing water from an exterior supply, except to make up waste. Water is used over again and again by aerating it in its circulation. Mr. O. B. Brush, M. Am. Soc. C. E., has written a paper which will be read before the Society, of experiments in forcing air into water by means of air-pump pressure at the Hackensack works, as he claims, with success.
