A filtration unit for a pool as described having a inlet spigot and an outlet spigot wherein the spigots are in fluid communication with each other and are adapted to slidingly engage a supply line and return line from and to the pool respectively. The spigots may include elastomeric sealing washers. The filtration unit may also include a primary filtration chamber and a secondary filtered chamber wherein the secondary filtered chamber has material suitable to collect scale discharge from an electrolytic cell. The filtration unit may include an electronics bay with the electronic control systems positioned such that it is cooled by water transcending the filtration unit. The unit may include a variable speed pump wherein operation at low speed leads to diversion of water from a primary filter and operation at high speed courses filtration of water through the primary filter. The filtration unit may also include an acid holding tank and acid pump for automatic dosing of water to lower its pH.
