They are top loading which makes it very easy to add chemicals. And extensions are available to increase tablet or stick capacity, in case you are away for an extended period.

    Automatic Chlorine Feeder

    The Pentair Rainbow 300 automatic off-line chlorine/bromine feeder has transformed my pool maintenance routine with its precision and ease of use. After years of manual chlorination, this device provides consistent chemical distribution without constant monitoring. I was initially skeptical about automatic feeders, but this model has proven to be incredibly reliable and efficient. The off-line design means no direct plumbing modifications, which was a significant selling point for me. Chemical distribution is even and precise, resulting in consistently balanced water quality. Pro tip: clean the feeder regularly and check the settings to ensure optimal performance. For pool owners tired of manual chemical management, this is an absolute game-changer. The reduced chemical handling also means less exposure to harsh substances. I've recommended this to all my pool-owning friends who want a more hands-off approach to maintenance.
