I think CarlD played around with a couple of types of liquid chlorine dispensers and didn't find one that worked well for him, unfortunately that information was lost with the server crash earlier this year. Hopefully he'll see this, though, and chime in.

There are always trichlor chlorinators you can get and connect, but you have to be really careful because trichlor pucks will drastically increase your CYA over the length of a summer.
