Like other CompuPool generic cells, the GRC20GH is more economical than its OEM counterpart. CompuPool is an established name in saltwater chlorination with more than 30 years in the industry. Another advantage of CompuPool generics is the clear housing, which makes it easy to ensure the cell is functioning correctly. This also helps in determining when the cell is in need of periodic cleaning, which can be done easily with a solution of water and muriatic acid.
