Chemical feeders are used to maintain sanitizer levels in your pool or spa. They come in different sizes to hold the different size chemical tablets. Larger ones are used for pools and smaller ones for hot tubs.
If you use a pool floating chemical feeder in your pool over the winter and keep it full, you will find that your pool in the spring will not be very green and will be much easier to bring up. You will not have to treat for algae and will save the expense of those chemicals. You will not have to be cleaning out the yucky gunk that comes from a green swamp instead of a clear pool.
It is important from a safety standpoint to make sure your chemical floaters are in good condition. Broken tops can allow access by a small child and possible ingestion of the chemical tablets.
