Brine rejection that drains from the newly formed ice is replaced by a weak flow of relatively fresh water, from the liquid region below it. The new water partially freezes within the pores of the ice, increasing the solidity of the ice. As sea ice ages and thickens, the initial salinity of the ice decreases due to the rejection of brine over time [Fig. 2]. While the sea ice ages, desalinization occurs to such a degree that some multiyear ice has a salinity of less than 1 PSU. This occurs in three different ways: Brine rejection occurs in the sea ice packs
Salt water chlorination is typically poured across the bottom and swept with the pool brush until it dissolves; if concentrated brine is allowed into the return-water system it can cause the chlorinator cell to malfunction due to overconductivity. Salt water chlorination produces an excess of hydroxyl ions whilst releasing chlorine from salt, which makes the pool alkaline (sodium hydroxide, NaOH, caustic soda). This requires the frequent addition of hydrochloric acid (HCl, also known as muriatic acid) to neutralise the alkalinity and convert the sodium hydroxide back into sodium chloride (i.e. table salt), which can be split by electrolysis again. Thus the consumable supplying
