Interline Simply Genius starter kit + 4 refills. Simple water care with the automatic dosing system. Chlorine dispensers are dangerous for children because they are often considered toys. The Simply Genius is mounted on the water hose outside the pool and is therefore inaccessible to children inside the pool. The fast-dissolving Aquafinesse tablet ensures the water feels soft. Protects sensitive baby skin. Provides crystal-clear water and regulates pH. Prevents bacteria from adhering to walls and floors (no slippery pool walls). Effective against algae formation, so no more green water. On average, one cartridge provides about a week of carefree water care and clean pool water. Suitable for garden pools up to 10,000 liters. Thanks to the included hose adapter, Simply Genius fits all commercially available pumps and sand filter systems and is the perfect replacement for your existing chemicals. Supplied with: a Simply Genius chlorine dispenser with universal connector for 32 mm and 38 mm pool hose, four extra cartridges, two hose clamps, an Aqua Finesse cartridge, and a child lock to close the system.
