The typical rule of thumb is to use from 1-2 lb (0.45 to 0.9 kg) of live rock per gallon (US) (3.7 liters) of aquarium water depending on the density of the rock – or filling the tank up 2/3 of the way to the top.

The aquarium was constructed from 41 acrylic panels – 26 panels for the outside cylinder and 15 panels for the inside cylinder for the elevator – which were bonded together on site. [7] With a diameter of about 11 m (36 ft) and a height of about 16 m (52 ft), resting on a 9 m (30 ft) tall foundation, it held the Guinness World Record for ...
As magnets affect water to a small degree, and water containing ions is more conductive than purer water, magnetic water treatment is an example of a valid scientific hypothesis that failed experimental testing and is thus disproven. Any products claiming to utilize magnetic water treatment are absolutely fraudulent. [1]
A number of medications and water treatments are used in this way. Salt is the most effective bath treatment, and is used to eliminate ciliated protozoan parasites (including ich in small fish); also used to curb the absorption of nitrite , and to reduce the osmotic pressure exerted by fresh-water on any hole in the skin or gill .
The Mote Marine Laboratory & Aquarium in Sarasota said in a statement that the 11-foot (3.3-meter) smalltooth sawfish died Thursday at the facility, where it had been undergoing treatment.
In 1955, UV water treatment systems were applied in Austria and Switzerland; by 1985 about 1,500 plants were employed in Europe. In 1998 it was discovered that protozoa such as cryptosporidium and giardia were more vulnerable to UV light than previously thought; this opened the way to wide-scale use of UV water treatment in North America. By ...
The advantage of an aquarium closed with a lid (rather than a permanently sealed plug, which is found in the base of an EcoSphere) is that if the system goes out of equilibrium, the owner can remedy conditions and prevent a complete die-off. Intervention to maintain good water quality allows a larger number of shrimp to live in the open system ...
