    Quick Question on Chlorinators

    Can anyone tell me why i cant put cal hypo briquettes/tabs into a chlorinator that is meant for TCCA? I seem to find that Cal Hypo feeders sell for more.

    Is this to do with scaling or are there other issues involved?

    Cal Hypo tablets dissolve much more easily than trichlor pucks. As such they can't use the same chlorinators.

    Don't add either product to a chlorinator that has been used for the other.

    I think this is also to do with the fact that trichlor and cal hypo don't get along.

    I live a few miles from a pool chemical manufacturer, a few years back they had a big fire when two chemicals came together.

    Re: Quick Question on Chlorinators

    Mixing chlorine types is dangerous. I'm not sure exactly what bad chemical reactions would take place, but I wouldn't want to find out first-hand.

    Also, trichlor tabs dissolve nicely, staying hard and crunchy as they slowly dissolve. Cal-hypo tabs sort of turn into a mushy mess, so the feeder has to be designed differently to work with them.

    The isocyanurates (stabilized chlorine) in the trichlor are acidic. When that acid hits the basic cal hypo;

    Oh right, now i see. Cal Hypo feeders seem rather expensive.
