The Model 300 automatic chlorine/bromine freestanding feeder not only saves time, but also reduces manual handling of chemicals. Years of customer satisfaction has proven the 300 to be an ideal choice for new or existing pools or spas. An external fine control valve lets you adjust the feed rate to meet specific pool or spa requirements. This is the perfect way to easily sanitize your pool or spa and create more time for enjoying them.
The Rainbow Model 320 uses large or small Trichlor or Bromine slow dissolving tablets to make sanitizing your new or existing pool or spa easy and automatic. Designed for installation in the return line, the Model 320 feeder dispenses sanitizer directly into your pool or spa, downstream of all equipment.
