[4] [5] [6] The brightness also depended on the concentration of salt in the water. [4] The switchboard built at Her Majesty's Theatre, London in 1897 had a dimmer scale of 0 to 10, whereas gas lighting only had 3 levels. [1] The salt water need to be refilled regularly, the metal electrodes corroded, and the dimmers emitted a strong smell.
A liquid rheostat or water rheostat [1] or salt water rheostat is a type of variable resistor. This may be used as a dummy load or as a starting resistor for large slip ring motors. In the simplest form it consists of a tank containing brine or other electrolyte solution, in which electrodes are submerged to create an electrical load.
Early examples of a rheostat dimmer include a salt water dimmer, a kind of liquid rheostat; the liquid between a movable and fixed contact provided a variable resistance. The closer the contacts to each other, the more voltage was available for the light.

Since it originates from deep water, it remains easy to care for, even without strong lighting. The algae radiates outward as it grows and will form dense fronds under good water quality and moderate lighting. [179] 5 in (12.7 cm) [179] Red wiry turf algae: Gelidium sp.
